A Brooklyn man is facing charges of assault and other crimes after authorities say he chased a woman while wielding a hammer and injured others in Queens earlier this month. The Queens district attorney also charged 42-year-old Shaleek Brunson with criminal possession of a weapon, endangering the welfare of a child and trespassing on Friday. Officials said Brunson approached the woman while wielding the hammer near the Queens Center Mall in Elmhurst around 11 a.m. on July 28. The woman ran down nearby Woodhaven Boulevard, taking refuge at the Jewish Institute of Queens, according to the Queens district attorney’s office. Officials said Brunson pursued her into the fenced-in schoolyard, pushing aside an 8-year-old boy who had been standing nearby.
