BOSTON (AP) – A Boston city councilor allegedly videotaped accepting a $1,000 bribe says he’s the victim of a “set-up” designed to entrap him and is planning make his case on the steps of City Hall on Monday.

Turner was arrested Friday and charged with one count of attempted extortion and two counts of making false statements for allegedly accepting cash from an undercover agent working with the FBI as part of a public corruption probe at Boston City Hall and the Massachusetts Statehouse.

He was taken into custody less than a month after his records were subpoenaed as part of the investigation into former state Sen. Dianne Wilkerson, who was charged last month after the FBI said she was photographed stuffing bribe money into her sweater.

After Turner’s arrest, the FBI released a photo allegedly showing him taking a wad of cash from the same confidential informant who said he paid bribes to Wilkerson in exchange for help getting a liquor license for a Boston nightclub.

Unlike Wilkerson, who released written statements but declined to talk publicly after her arrest, Turner says he’ll hold a rally on the steps of City Hall at 2:30 p.m. on Monday. A half-hour later, Turner’s colleagues plan to discuss his arrest at a special closed-door meeting.

“I’m calling a press conference for the press and the community to come to the steps of City Hall where I will talk in even more depth about the picture in the paper, about what I believe is going on in this, what I think is a set-up,” the outspoken five term city councilor told WHDH-TV.

Turner, free on a $50,000 unsecured bond, described his arrest as part of a “sting operation in order to try to entrap me.”

“The only recourse to protect the reputation that I have struggled to build over the last 45 years, a reputation of integrity, is to go on (the) defense,” he said.

Wilkerson was arrested Oct. 28 and indicted last week on eight counts, including allegations she accepted $23,500 in bribes for arranging a liquor license and land transfer for an FBI informant and undercover agents she thought were businessmen.

The arrests of the two high-profile African-American politicians have been met with shock and anger in the city’s black community.

Until her resignation last week, Wilkerson was the only black member of the state Senate. Turner, who represents Wilkerson’s neighborhood on the city council, is a Harvard-educated member of the Green-Rainbow Party and has served on the City Council since 2000. Before that, Turner was a prominent community activist.

U.S. Attorney Michael Sullivan brushed aside any suggestion that black officials were being targeted.

“We’re blind to color when it comes to the evidence,” Sullivan said Friday.

Leaders in the black community say they were even more shocked by Turner’s arrest. Wilkerson had been plagued by a series of self-inflicted troubles during her eight-terms in the Senate, once being sentenced to house arrest in December 1997 after pleading guilty to failing to pay federal income taxes.

Rev. Hurmon Hamilton, pastor of Roxbury Presbyterian Church, said there was never a “hint of impropriety” from Turner, who is beloved by the community.

“They are shocked, but they are trying to find out what the authentic details are,” said Hamilton, who called Turner “a strong and consistent voice for justice” and cautioned against a rush to judgment.

Hamilton said that while he believes black officials should be held to the same high standards as anyone else, he would be concerned if the arrests stop at black elected officials.

“If it (corruption) is a regular practice, then I do expect if it’s an honest probe … then there should be more than just black officials arrested,” he said. “That’s not to say we give black officials a pass, but I am asking them to be completely comprehensive.”

An affidavit said Turner was taped in August 2007 taking a wad of money from the informant while in his district office, then denied the payment when confronted by FBI agents on the day Wilkerson was arrested.

The informant attempted to make a second payment in September 2007 just outside the City Council chamber but could not arrange time alone with Turner, according to the affidavit.

The affidavit summarized what an FBI agent said was “a portion of a covert investigation into the criminal activities of Turner and others.”

A similar FBI affidavit filed in connection with Wilkerson’s case refers to Boston Mayor Thomas Menino, City Council President Maureen Feeney, Senate President Therese Murray and other city and state officials – most of whom have acknowledged receiving subpoenas. Menino, Feeney and Murray have denied any wrongdoing.

U.S. Attorney Michael Sullivan said Friday that Menino, other members of the Legislature and the governor’s office weren’t targets of the probe.
