Columbia Police arrested four teenagers they say were involved in four robberies from April 1-2.
The report said a male victim told CPD Investigators that three black males followed him on foot as he walked alone on Oak Street shortly after midnight on April 1, 2013.
He adds that they pointed a gun at him to demand money. When he told them he didn't have any, he says a gun was pointed at his head while the suspects searched his pockets. The suspects allegedly stole several cans of beer from him then ran away.
