A man stepping off a METRO light rail train was punched in the face and left with a black eye, a cut and fractured nose.

"I looked down at my phone to read a text message and the next thing I know...POW!" said Vincent Gonzalez, who got suckered punched. "I looked behind me and saw a person standing there yelling at me and cursing at me."

Police said Gonzalez wasn't the only person punched that day and both attacks were unprovoked. They are now trying to identify a man seen in some surveillance pictures who is believed to be the suspect. 

"I worry about this person continuing to do this," said Gonzalez. "I worry about him doing this to an elderly person, a pregnant woman, a child, anybody," Gonzalez said. 

METRO police officers are asking anyone with information to contact them or call Crimestoppers at 713-222-TIPS.

"I'd like to tell the public, don't walk and text, keep your eyes looking forward, look where you're going and look at the people around you," Gonzalez said.
