Durham Regional Police say two brothers have been arrested after they allegedly sprayed armoured truck guards with bear spray during a failed robbery in Ajax.

According to police, the two suspects ambushed the guards when they were making a delivery at an Ajax bank. Police say after spraying the guards, the pair fled empty-handed.

The guards suffered minor injuries during the incident.

On Monday, investigators say search warrants were executed at two Toronto-area addresses and one suspect was arrested without incident. The second suspect, police say, was later arrested at a separate location in Toronto.

Oluwasheun Hastings, 29, and Kunle Banjoko, 25, have been charged with robbery with a weapon, disguise with intent, and possession of a weapon to commit an offence.

Anyone with new information about this incident is asked to contact Det. McKinnon of the Major Crime Robbery Unit at 1-888-579-1520 ext. 5362.
