Police have cordoned off a block of flats in Oxford as forensics have been called to investigate the incident.

Pictures show the block of flats at Warren Crescent in Headington taped off with one of the building’s windows smashed and a number of police vehicles on the scene.

This is the second residential street in Oxford that has a police presence on it this morning (Monday, August 11) as the front garden of a home on Saunders Road in Cowley has also been taped off.

One eyewitness told the Oxford Mail a "house had been taped off" at around 8pm yesterday (Sunday, August 11) with five police vehicles at the scene in Cowley.

Officers remain at the scene this morning with only the front garden of the home taped off.

Another resident, who also asked to remain anonymous, said she and her husband heard a "loud bang" at around 4.30pm yesterday afternoon when they were sitting in the garden.

She added that they heard "a lot of sirens" before armed police arrived at the scene.

At around midnight, she said forensics were at the scene.

She said: "It’s a bit worrying in your own street.

"I’ve never seen anything like this before outside the doorstep."
