Witnesses reported seeing men armed with machetes chasing a person following a car crash in a Birkby street.
Residents of Arnold Avenue said the armed occupants of a car abandoned the vehicle in order to chase a person on foot.
The car was left in the middle of the residential street, which had cars parked on both sides, so traffic was totally blocked for a time during Wednesday evening.
Police arrived on the scene shortly after and later said the incident had been a road traffic collision.
A spokesperson for West Yorkshire Police said: “We were called to a report of a two car road traffic collision at 8.16pm to Arnold Avenue.
“No one was injured.
“Drivers made off from the scene.”
