Mr Broadhurst, whose 23rd birthday would have been yesterday (Wednesday) was taken to hospital with a serious stab injury but was pronounced dead an hour later.

A second man, aged 46, who lives in Chelmsley Wood, suffered a hand injury and was also taken to hospital.A police spokesperson said: “It’s understood the incident was the culmination of disorder that initially broke out at nearby St Anne’s Social Club and then spilled over into Nineacres Drive.”

Nineacres Drive, the street where Mr Broadhurst was found, was cordoned off from Sunday to Wednesday while forensic investigators scrutinised the scene. Flowers and notes littered the adjacent Bosworth Drive, the road with the social club on it. And last night (Wednesday) at 6pm, friends visited the area, now known to them as ‘Harry’s Spot’, to pay their respects and wish him ‘happy birthday.’

Tributes to Mr Broadhurst, who was a company director of his steel manufacturing business, Mount (UK) Ltd, have also poured in on social networking website, Facebook.

More than 300 people have signed up to a page dedicated to his memory and his sister, Millie, left this message: “Words can’t explain how much I love you, and I miss you that much it hurts. We all love you and we won’t go a day without thinking of you, you’re our everything.”

In the comments section of  another website, one of his cousins, Issy Rowles, says: “The world lost an angel. Harry Broadhurst, such a kind person, you were only trying to do the right thing. Nobody can imagine being in a world where you’re not, but you’re in a better place now it’s such a shame that you had to leave us all behind. It hurts  an unreal amount to know that I can’t see you. Even though you’re gone you will never ever be forgotten, you made such a huge impact on so many people.”

The afternoon boxing meet at St Anne’s social club, where police believe the disorder erupted, was described by residents as a family event.
