A man who was tragically killed by an oncoming Tube train as he attempted to save his brother has been named as Nick Mann.

Mann, 35, from London, died of severe head injuries after he attempted to save his 32-year-old younger brother, Robert Mann, 32, from being struck by a train at Old Street station in central London, the British Transport Police confirmed today.

Both men were rushed to the Royal Free Hospital in north London after the incident, where Nick died on Saturday night. Robert, who lives in Manchester, remains in a critical condition.

A friend of Nick, who asked to remain anonymous, paid tribute to the avid football and music fan today, and told The Evening Standard he was “one of the best dudes I knew”.

He added that it did not surprise him that he had attempted to save his brother's life.

“He would have done anything for anyone,” the friend said, adding:“He was one of the most passionate people I've ever known. He was a great dude and he'll be sorely missed.”

Josh Retallick, who had been friends with Nick for eight years and works at a live music pub in Camden, described Nick, who curated the As Short Fanzine About Rocking (ASFAR music fanzine, as a “hero of the DIY music scene”.

The British Transport police have called the incident a “tragic accident”, and said they are not treating it as suspicious.
