Robert Rinder has said he feels an "overwhelming sense of sadness" for a group of thieves who mugged him.
The barrister and TV judge said he had his phone "grabbed" from his hand on Wednesday evening in north London.
On Thursday he tweeted: "After the rage, I feel an overwhelming sense of sadness for these boys because I've seen where their path leads.
"In the meantime we need to champion, train & fully resource our brave police officers - who come from EVERY background - to work with ALL communities to protect us."
On Wednesday Rinder said the thieves, who were wearing balaclavas, "laughed as I shouted to drop it".
"I'm in shock but am insured & privileged," he added.
"Others are less lucky. Help me find these people & stop them (financial reward)."
A number of famous faces sent messages to Rinder after the mugging.
Channel 4 News presenter Krishnan Guru-Murthy tweeted: "Main thing is you're ok. Tried texting you but.....doh. Call if you need anything."
Singer Beverley Knight added: "I am so sorry Robert. I don't care about privilege, nothing about what happened to you is ok."
The Metropolitan Police said officers are investigating a report of a theft at around 8.40pm on Wednesday in Finchley Road.
A statement said: "Three males dressed in black approached the victim and took his mobile phone. Inquiries are ongoing. No arrests at this early stage."
