William, second in line to the British throne, spent a night near Blackfriars Bridge in central London last week in an event organized by homeless charity Centrepoint.
Centrepoint's CEO, Seyi Obakin also spent the night alongside the prince and said it was a difficult and dangerous experience.
"There was no shielding from the bitter cold, or the hard concrete floor, or the fear of being accosted by drug dealers, pimps or those out to give homeless people a good kicking," Obakin said.
