Pablo Roman, 19, of Worcester, faces charges of carrying a firearm without a license, possession of ammunition without an FID card, disorderly while armed, and trespassing, Worcester police said.
A woman called police around 12:15 a.m. after she saw a man cock a pistol outside of the Free Play Arcade on Union Street before shoving the gun into his waistband. Officers approached Roman near the Worcester bus hub on Foster Street, but he ran away before they could stop him, authorities said.
Police chased him down and found the pistol stuffed into his pants. He was arrested and charged.
No one was reported injured.
