The Boston Police Department reports a man charged with robbing the Tedeschi convenience store at Columbia Road and East Cottage Street Thursday morning also robbed the place earlier this week.

Police say officers on another case stopped what they were doing when they saw a man running across the store's parking lot and being pursued by two other men around 9:30 a.m.

Police say the officers quickly caught up with the pursued guy and stopped him for a discussion:

"At that time, officers noticed the white male suspect holding money in his right hand and a firearm in his left jacket pocket. Officers then received information from a police dispatcher that an armed robbery had just occurred in the area. As the dispatcher relayed the message, the suspect Gary Accomando, 58, blurted out 'I did the robbery, but the gun is not real.' Officers retrieved what appeared to be a silver colored firearm from the male suspect's left jacket pocket.

Accomando was charged with armed robbery and assault by means of a dangerous weapon.
