Wanted man arrested north of Brisbane

A man has been arrested after a police hunt north of Brisbane.

The man allegedly cut a person with a knife during an argument at a Chermside Road address in Mango Hill about 6.30am on Monday.

A second argument is believed to have taken place on Mercury Parade.

Helicopters and the dog squad were used to search for the man. A witness claimed he was armed with a gun but police are yet to confirm this.

Mango Hill State School and Kids Capers Childcare were locked down for the duration of the operation.

A police spokesman said there was no threat to the school or childcare centre, and they were just near the search location.
