Three teenagers have been arrested in connection with the murder of a 15-year-old found stabbed yards from his home.
Keelan Wilson was found injured following reports of violent disorder involving a group of people in Langley Road in the Merry Hill area of Wolverhampton at about 11pm on May 29.
West Midlands Police have said three boys, aged 14, 15 and 17, were arrested on Thursday morning and are due to be questioned by officers.
A 16-year-old was also arrested last week and was released on police bail pending further enquires.
Detective Inspector Warren Hines, from the force’s homicide unit, said: “This is a further significant development in our investigation.
“We continue to work on a number of leads and I am extremely grateful to everyone who has provided us with information.”
Mr Hines added: “The tragic death of Keelan was unnecessary and tragic and we are working round the clock to understand what happened and get answers for Keelan’s family who are being kept updated with the latest developments.”
The force have appealed for anyone with information to come forward.
