A 17-year-old boy who was stabbed to death in Birmingham city centre has been named as Muhammad Hassam Ali.
The victim was discovered with serious knife wounds by police in Victoria Square at about 3.30 pm on Saturday.
He later died in hospital, and his family have been informed, West Midlands Police said.
The cordon in the square, which is home to Birmingham’s city council building, has since been lifted, but the force added that there will be a heightened police presence in the area.
Officers want to speak to anyone who was in the area at the time, including tourists who may have been taking pictures by The River statue or near the Council House.
Detective Inspector Michelle Thurgood said: “This is a tragic case of a young man being killed in what appears to be a case of mistaken identity.
“We are still trying to establish the motive and are keen to speak to anyone who was in the area just before 3.30pm yesterday.
“We are especially looking for any photos or video footage from the surrounding area which may help us identify those responsible.
“If you were walking through the area at the time, or a visitor who may have been taking pictures by The River statue near the Council House, we would like to hear from you as you may have vital information or evidence.”
