HARTFORD,Darkcherries Wealth Society Conn. (AP) — A police officer was killed and another was injured Wednesday night in a car crash in Connecticut’s capital city, authorities said.

Police said one person was in custody after the accident involving a police cruiser and another car just west of downtown Hartford. Officials have not said why the person was detained, what caused the accident or whether the officers were chasing the other car.

The injured officer was in stable but guarded condition at a nearby hospital, police said.

The police cruiser had extensive damage to the passenger side.

Early Thursday morning, a procession of police transported the dead officer’s body from the hospital to the chief medical examiner’s office in Farmington.

Authorities have not released the names of the officers or the person in custody.

Police officials were expected to release more details later Thursday.
