Grenville Ontario Provincial Police urge parents and their children in Kemptville to be alert after two preteens were approached and, police say, could have been abducted.

The first one took place on Jan. 13, police say, when a 13-year-old girl walking in Kemptville on Preston Street. A man in his 50s or 60s followed her to a local hardware store, where she called home. Her parents told her to wait at another location, and the man continued following her to that spot, police say.

On Jan. 28, a 12-year-old boy was walking home from school on the same street when a man in a white minivan drove up to him. The man told the boy his mother had sent him, police say, and tried to encourage the boy to get in the van. The boy refused.

In that case, the man was described as in his 50s or 60s with white hair and a receding hearline, wearing sunglsses and a black winter coat.

Anyone with information should contact Grenville County O.P.P., Kemptville Detachment at 613-258-3441, O.P.P. Communication Centre at 1-888-310-1122 or Crime Stoppers at 1-800-222-(TIPS).
