#Good Samaritan uses martial arts to thwart attempted kidnapping

A New Yorker put his martial arts skills to use and thwarted an attempted baby-snatching in a Big Apple park last week, pinning the perp down for 15 minutes until authorities arrived, he said Monday.

Brian Kemsley, a 33-year-old trained in jiu-jitsu, stepped in when he saw a man trying to grab a baby inside a stroller from a woman who was also holding a 4-year-old child in her arms last Monday in Madison Square Park.

“It’s not a matter of stepping in it’s a matter of duty, when you see a woman and her child screaming,” he told PIX11, which first reported the incident.

The NYPD said it responded to the park that day at around 3:35 p.m. for a report of an emotionally disturbed person, who was taken into custody and to Bellevue hospital for psychological evaluation.

The foiled kidnapping was captured on cellphone footage showing Kemsley tackling the man to the ground and holding him there.

“Here’s the thing, I don’t enjoy jujitsu, I don’t think training is particularly fun, but I have a lot of respect for it as it is absolutely essential in a street fight and self-defense,” he said in an Instagram post about the incident.

“I’d like to point out that when it comes to community security, that smashing someone should not be the priority,” he added in another post.

“We’re not suppose to show up with sticks and start beating people. The priority should always be to defuse the situation safely and as non violently as possible so we do not escalate the situation.”

Kemsley told Fox News on Monday that the mother later came back to the park to thank him.

“I’m happy she did that,” he told the outlet.

The good Samaritan didn’t immediately return a call from The Post on Monday night.
