Riders grab thug who mugged vic on subway

A group of straphangers chased down and caught a vicious robber who punched a hearing-impaired woman in the face and stole her phone on a Brooklyn subway train, police and sources said.

The attack was one of two serious assaults in the city’s subway system on Friday. In the second, a commuter was punched several times in the face and knocked to the platform in the Times Square station.

The victim in the Brooklyn attack was checking her phone on a Coney Islandbound D train going into the 36th St. station, when Kirilm Dudichenko, 33, motioned for her to give him the phone.

When the woman ignored him, Dudichenko grabbed it and threw it to the floor of the train.

The woman asked to have the phone back. Dudichenko pushed her and then punched her in the face several times.

Dudichenko then grabbed the phone and ran from the train. Several straphangers gave chase, caught him and held him for police.

Medics rushed the victim to Coney Island Hospital where she was treated for bruising and swelling to her face.

Dudichenko was charged with robbery and assault. He has numerous prior arrests, including an assault Oct. 9 in Sheepshead Bay in which he punched a 66-year-old man several times.

A few hours earlier, about 9 a.m., a 65-year-old woman was punched several times in the face in the Times Square subway station. She dropped to the platform, and the suspect fled.

The victim was taken to a medical care facility to be treated for bruises.

Police sources identified the suspect as Jacob Millier, 30.

He was described as 6-feet tall, 220 pounds with black hair and brown eyes.
