Boston police said yesterday that officers have arrested one man and are looking for another who allegedly used a machete and a hypodermic needle to rob a Brighton man in his home Wednesday night. Mark Lidsky, 22, of Brighton, was arrested on charges of armed assault in a dwelling, home invasion, armed robbery, and assault and battery by means of a dangerous weapon, police said. The victim was taken to St. Elizabeth’s Medical Center after his chest was scratched by the machete and his hand was punctured by the needle during a brief scuffle with the robbers, said police spokesman Dave Estrada. He said police believe they know the second suspect and are looking for him.
