WARE, Mass. (AP) – A teenager was treated for injuries that may have been caused by a homemade bomb Thursday in this western Massachusetts town.

The state police bomb squad investigated at a multifamily home after the teenager was injured, authorities said.

“We’re positive there is some type of homemade-type of device, possibly incendiary in nature,” Police Chief Dennis Healey said.

There was no immediate information on the teenager’s injuries or identity.

Police responded to the West Main Street home near downtown around 4 p.m. Several homes were evacuated and traffic was routed away from the location.

There were no immediate arrests, police said.

State Fire Marshal Stephan D. Coan said authorities were investigating.
