The presenter is currently in the UK filming season two of Adam Richman Eats Britain.
In the social media post, Mr Richman said after wrapping filming in Tottenham, north London, he received a notification via an app that his keys were nearby, around Muswell Hill Playing Fields.
With the help of a bodyguard, he said they spent three hours during the evening searching for his items and that they even heard the tracking device on his keys.
Mr Richman said his possessions ended up being beyond a metal fence that his bodyguard climbed over and tracked down.
He added the items were found scattered on the ground, and what was recovered also included his bag, glasses, house keys and a children’s book from his mother.
Mr Richman said: “There are bad people about.
“But there are shining lights to be found as well.
“I found one.
“There goes my hero.”
