TORONTO - Police say they have arrested a second man who allegedly filled a colleague's water bottle with engine coolant at a BMW dealership.

Toronto police say they charged a 20-year-old man with attempted murder after he was arrested on an unrelated matter in Belleville on Friday.

Last week, police say a dealership employee took a sip from his bottle and realized it wasn't water.

He then went to a pharmacy for treatment and then to a hospital where he was cleared of any ill effects.

Police say they reviewed security footage of the dealership that showed two men taking the water bottle and then returning it.

The 20-year-old Toronto man was charged with attempted murder and administering a noxious substance. Police previously charged a 34-year-old man in relation to the same incident.
