About 30 armed police descended on Petersfield Avenue, Harold Hill, last night after a man allegedly started firing shots in the street.

The man was arrested at the scene and remained in custody as of Thursday evening. He has not been charged.

Maria Hayllar, who runs the Heavenly salon, said a bullet hole was left in her double glazed window and a lottery sign next door to her was destroyed during the incident.

“[A shot] went through both panes,” she said. “There were clients here. It could probably have killed someone.”

Fortunately, no one was hurt.

Within 10 minutes, about 30 armed police were swarming the area. Petersfield Avenue was closed off until about 6.30pm.

Police described the weapon as a “gas-powered pellet gun”.
