Havre de Grace police say a Pennsylvania man, arrested last month on charges of stealing from cars, has also admitted to trying to rob a Havre de Grace gas station in June.

Timothy Michael Hackman, 25, of the 400 block of South Little Britain Road in Peach Bottom, Pa., was arrested July 7 and charged in connection with a series of car thefts in the Gracecroft neighborhood in Havre de Grace.

Police said GPS systems, loose change and iPods were among the items stolen.

Hackman is charged in the case with two counts each of theft less than $1,000 and rogue and vagabond and one count of theft scheme $1,000 and $10,000.

Police are asking anyone in the Gracecroft neighborhood whose valuables may have been stolen to call Havre de Grace Police Department’s criminal investigative division, 410-939-2121. Some of the property found has not been claimed.

While talking to them about the car thefts, police say Hackman admitted he tried to rob the BP gas station in the 1000 block of Pulaski Highway on June 15.

At about 2:10 a.m. that day, a man entered the gas station and hit an employee on the back of the head with an object.

He also hit the employee in the left forearm with what appeared to be a piece of lumber, police said. The suspect then took off on foot.

In the gas station case, Hackman has been charged with armed robbery, possession of a deadly weapon with intent to injure, first- and second-degree assault and reckless endangerment.
