Mr O’Halloran’s murder, the 59th in the capital so far this year, left those who knew him stunned.
Hitesh Patel, 62, a shop owner at Greenford station, told The Telegraph that Mr O’Halloran, who he said had three children, would often play the accordion on his mobility scooter outside Tesco and Greenford station to raise money for Ukraine victims.
Mr Patel said: “He was Irish and he had a white beard and he used to play music outside.
“People used to call him Mr Bond because he would drive around on his scooter and rev the engine.
“He has lived here a long time. Maybe 20 years. I know his wife as well. He had quite a few sons I think.
“Every day he would come and play here. We knew it was him because he had a Ukraine flag on his scooter and he used to raise money for charity.”
