Two men were shot and another stabbed when violence flared in Wolverhampton.
One victim, aged 20, had been riding a bike when a car pulled up and two men jumped out, stabbing him in the leg and buttocks.
Minutes later, two men arrived at Wolverhampton's New Cross Hospital with gunshot pellet wounds to the shoulder and arm.
The chain of events began when officers were called at 4.40pm yesterday to reports of a car being damaged in Bilston.
The stabbing happened on Hillside Gardens in Eastfield at around 9pm.
The men who were shot are believed to have been injured during a dispute in the Eastfield area when a shot was fired at a house on Deansfield Road.
A 17-year-old youth was arrested from Deansfield Road on suspicion of assault a short time later.
It comes just days after a shot was fired and a youth was stabbed when violence flared in Lichfield Street in Wolverhampton city centre.
Detective Chief Inspector Pete Dunn, based at Bloxwich, is leading the inquiry into last night's violence.
He said: “This appears to be a dispute between two groups, which has led to three people suffering injuries – thankfully none of them are life threatening although it could easily have been more serious.
“We are still piecing together all of the information regarding the events of last night and we want to hear from anyone who was in the Eastfield area and may well have witnessed all or part of these crimes.
“Violence such as this has no place on the streets of the West Midlands. We will be actively seeking those involved in armed criminality within our communities, whilst extra officers will be on patrol to ensure no further incidents occur and those responsible are brought into custody.
“Local officers are in the area today, speaking to residents and offering some reassurance to those concerned by what happened.”
Witnesses should call police on 101.
