Six teenagers arrested on suspicion of murdering a 16-year-old boy who was stabbed to death outside a party at a social club have been released on bail.
Ben Morutare, from Walsall, West Midlands, was knifed in the leg during a disturbance at the Smethwick Home Guard and Old Comrades Club in Oldbury Road, Smethwick, during the early hours of July 28.
West Midlands Police said a 19-year-old man from Dudley, two 18-year-old men from Birmingham, an 18-year-old man from West Bromwich and a 17-year-old youth from Birmingham who were arrested on Thursday evening had been bailed until a date in September.
An 18-year-old man from Ladywood, Birmingham, who was arrested after voluntarily attending a police station, was also bailed to the same date. A seventh teenager, an 18-year-old man who was arrested in Dudley on Wednesday, was bailed earlier this week.
A police spokesman said: "All seven are subject to strict bail conditions including an overnight, electronically-tagged curfew at specified addresses, and daily reporting to police stations."
The victim, described as "protective" and "lovable", was taken to Birmingham Children's Hospital.
In a statement released through police his family said: "Ben was a beloved son, brother and nephew. Ben was loved dearly by his family and many more who knew him.
"One thing our Ben never forgot was to constantly remind his family, especially his mum, how much he loved and cared for them. He was a protective son and brother. Ben would never hurt anyone, he was such a lovable child. Words cannot express how much we miss our Ben and the pain we are enduring."
Urging witnesses to contact police, the family added: "We fully appreciate all the witnesses who have come forward so far and we kindly ask and encourage other people who may have information to come forward."
Detective chief inspector Bob Hazel said: "We've spoken to a number of people who were at a party at the club on the night but we believe there are many more who may have seen something and have not yet been in touch. People may have taken pictures during the night, or recorded the fight which broke out outside on their mobile phones and we now ask them to do the right thing and contact us to pass this on."
