A 16-year-old boy has died after being found stabbed.
Police found the teenager after being called to reports of a disturbance at the Smethwick Home Guard and Old Comrades Club in Oldbury Road, Smethwick, at 1.30am on Saturday.
The boy was taken to Birmingham Children's Hospital but died later from his injury.
West Midlands Police have launched a murder inquiry and are urging people with information to come forward as forensic investigations continue at the scene, which has been sealed off.
The boy has not yet been named and a family liaison officer from West Midlands Police is supporting his relatives, a force spokesman said.
A post-mortem examination is due to take place later.
Local officers are carrying out inquiries in the area and extra patrols are in place to reassure the local community, the force spokesman added.
Detective Inspector Warren Hines, of West Midlands Police, said: "It is believed there were a large number of people at the club last night and early this morning, and I am appealing for anyone who saw what happened and who hasn't yet spoken to police to come forward."
Anyone with information is urged to contact West Midlands Police on 101 or Crimestoppers anonymously on 0800 555 111.Suggest a correction
