A former Boston police officer has found himself on the wrong side of the law.
Isaac Thornton, 43, of Arlington, was arrested outside a club early Saturday morning, accused of planning to shoot a police officer.
Thornton was at the Dublin House at 7 Stoughton Street in Dorchester when someone overheard him say he was carrying a firearm because he was going to shoot a police officer.
Boston Police were called to the Dublin House and when they arrived, Thornton was hiding in a doorway next door.
Officers approached him, a fight ensued, and he was taken into custody.
Police discovered a firearm, a round of bullets, and a police badge in his possession.
Thornton has a past record of trouble with the law.
Back in July of 1991, he faced charges for shooting a Dorchester teen at The Gallery nightclub in Roxbury.
Thornton was cleared of all charges, but has since been terminated from the Boston Police Department.
He is being held at District B2 in Roxbury and faces several charges including unlawful possession of a firearm, unlawful possession of ammunition and carrying a loaded firearm
