Police have taped off a property at the corner of Stanmore Rd and Hereford St.

The police say cordons are in place while they work out what has happened.

More information is expected from police this afternoon.

One local resident told the Herald that police are often in the area.

"The gangs are taking over and they don't seem to care," he said.

"It's worrying because there is a lot of genuine decent people around and it's just a minority that is doing all the damage."
