The Boston Police Department reports arresting a man they say got away mainly with bruises and cuts from a beating supplied by workers at the Welles Liquor Mart after they changed their minds about just handing him the money he demanded Thursday night.

According to police, Sean Brown, 38, walked into the 1772 Dot. Ave. store around 8:30 p.m. yesterday, said he had a gun and demanded money: "According to store employees, after giving the suspect an undisclosed amount of money, an altercation between the suspect and two store employees ensued. The altercation spilled out to the sidewalk and ended when the suspect fled on foot towards Lonsdale Street. During the altercation, the store employees state that the suspect was struck several times."

Police say officers initially couldn't find Brown. Around 11:15 p.m., however, officers responded to a call for an injured person at Florida and Mallet streets a couple blocks away: "On arrival, officers observed a black male, not suitably dressed for the elements, suffering from what appeared to be lacerations and bruises to his head area."

The man, who turned out to match the description of the attempted-robbery suspect, was taken to Boston Medical Center with non-life-threatening injuries - and a police escort - police say. He was charged with armed robbery.
