Two young children were approached by a strange man around 4:30 Friday afternoon after getting off their bus at the Gates of Rochester apartment complex on 41st St NW.

The children - a 7 year old girl and her 6 year old brother - told police the black, older man showed a knife and grabbed the boy by the shoulder. At the same time, a black woman with the man began taking photographs of the children. The children were able to get away and ran home.  

The children are students at Riverside Elementary.  Police say they also told staff at the school they were videotaped by a woman at their bus stop Friday morning. Police initially reported a woman was seen videotaping students at the school Friday morning.
