MISSISSAUGA, Ont. -- A man in his 20s is in police custody after a WestJet flight from Halifax to Calgary was diverted to Toronto's Pearson airport on Wednesday evening.

Peel Region police received the call around 7 p.m. about an unruly passenger on board WestJet flight 231.

The plane landed at Pearson about 90 minutes later and police say the male suspect was arrested without incident.

WestJet did not immediately respond to a request for comment, but the airline tweeted Wednesday evening that "all guests are safe."

It also confirmed flight 231 was diverted to Toronto.

Sgt. Adrian Taylor of Peel Region police says charges will likely be laid but did not elaborate.
