An empty terraced house in Harehills that has previously been used by drug dealers could have been shot at.
Police are investigating whether damage to the door of the empty property on Bexley Terrace was caused by a shotgun being fired at it.
West Yorkshire Police said:
"At about 8.30am today police attended at an address in Bexley Terrace which had previously been boarded up due to links to drug dealing and anti-social behaviour.
"Officers found damage to the door which suggested a possible shotgun discharge. No-one was present at address.
"A scene has been put in place to undergo forensic examination."
Harehills has experienced a spate of violence in recent weeks, including shootings and street brawls, some of which are being treated as linked.
In early July, seven men were arrested after a fight outside a grocery store.
A house in Ashton Avenue was targeted in June, when shots were fired at the property when it was empty, and a 17-year-old girl received minor injuries when shots were fired through the window of a house on nearby Ashton Street in what is thought to be a linked attack. The Ashton Avenue house was again targeted a few weeks later, when arsonists set fire to a sofa outside the property.
In a separate incident, a 17-year-old boy was shot on Pasture Road on July 16.
