Harry Styles has revealed more details about what happened when he was robbed at knifepoint on Valentine’s Day.

In an interview with "The Howard Stern Show" on Sirius XM Radio, the singer, 26, said he was walking home from a friend’s house in London when a group of men with hoods and covered faces began following him.

“The guys cross the road and, I’m like, ‘Oh, that’s weird,’” he said. “I cross the street again, and they cross the street again, and I’m like, ‘Oh, for f---’s sake, I think I’m about to get robbed.’”

Styles said the men approached him and asked, "'Can we talk to you for a minute?' And there's nobody around, my heart's pounding." He said the men first tried to offer him marijuana, and when he refused, they surrounded him. When he saw they had knives, he gave them his cash.

Then, they asked him to unlock his phone, which contained his contact list, music videos, unreleased song lyrics and other personal information. Styles refused, and when they told him he had 10 seconds to unlock his phone, he considered throwing the device into a nearby pond.

But then he saw a chance to escape. 'I just felt an opportunity. I just sprinted, ran,' he told Stern. He quickly moved into the road and tried to flag down a driver for help.

“I ran into the road and I tried to stop a car,” he recounted. “Obviously if a mad man runs into the road and tries to get in your car you’re not gonna let them in, so they don’t let me in.”

After that, he just kept running toward his home, and luckily the men didn’t pursue him further. He soon filed a police report, and during his recent visit to the "TODAY" plaza, he reassured fans that he’s doing OK.

And, as he told Stern, this frightening incident hasn't deterred him from being out and about on his own.

"I went walking again the next day, because I didn't want it to stop me walking," he said. "I walk a lot of nights when I'm home because I really like it."
