The Ontario Provincial Police have found a brother and sister who were possibly abducted from two different schools today.

Toronto police said earlier that the siblings — a 10-year-old boy and a 12 year-old girl — may have been taken by their estranged father.

Toronto police Const. Victor Kwong said the OPP boxed-in a car west of Cambridge, Ont., and the driver of the vehicle was taken into custody.

Earlier, police alerted the public to be on the lookout for a four-door silver Honda Civic.

Cambridge OPP Sgt. Peggy Gamble said a citizen reported seeing a car matching the description in Guelph and officers intercepted it near a highway exit in Cambridge.   

"We were unaware of whether the suspect would try and flee the first officer," said Gamble. "As a precaution we boxed in the suspect and brought it safely to the left shoulder."   

Gamble said she believed the group was headed to London.

Both children were found safe and in the vehicle, police said.

On Twitter, Toronto police thanked the person who recognized the vehicle and alerted police after listening to media reports.

Kwong said they were still trying to determine if this was an abduction or a miscommunication.
