Television presenter Ben Fogle has escaped with only bruises after fighting off a mugger.
The serial adventurer wrote on Twitter how he had fought back when a chancer tried to snatch his briefcase.
He said: "Dear Mr Mugger. You picked on the wrong man. Enjoy the black eye. Love Ben."
The tweet to his 105,000 followers prompted numerous concerned messages from followers.
But the 40-year-old used the attention to reassure fans and shine the spotlight on the international effort to rescue nearly 300 Nigeria school girls.
He added: "Thanks for concerned messages. I'm fine. Suit scuffed and knuckles bruised. WAY more importantly #BringBackOurGirls #NigerianSchoolgirls"
In addition to television presenting, Fogle's expeditions have included rowing across the Atlantic and racing to the South Pole together with Olympic rowing gold medallist James Cracknell.
