Thursday, June 26 11 p.m. A man attending a conference on campus was walking outside of Cullinane Hall when he was approached by four youths aged 15 to 17 years old. They demanded his money, and one of them was holding a knife. The accosted man gave them his wallet after he said there were some important papers inside of it that he needed. The youths dumped the wallet, took the money and fled. The man called NUPD immediately and officers spotted four suspects a few minutes later. The group split up when they were running away, and officers apprehended a 15-year-old and a 17-year-old — neither of them had the knife or the money. The man who was accosted could not indicate whether the apprehended youths were the ones who took his money or had the knife. Both boys are residents of a group home in Jamaica Plain. They were returned to the home and the investigation is continuing to identify the other suspects.
