A Worcester man accused of a violent crime spree, including allegations of rape and armed robbery and threatening to “spray’’ police officers with an assault weapon, was ordered held without bail during his arraignment Wednesday in Worcester District Court.

Antonio Damon, 35, pleaded not guilty to charges that also included kidnapping, carjacking, assault to rape, and assault with a dangerous weapon, District Attorney Joseph D. Early Jr.’s office said.

Damon is due back in court for a dangerousness hearing on Aug. 22. His lawyer, Sean McGinty, could not be reached for comment.

Damon is alleged to have committed an hour-long crime spree late Tuesday afternoon through downtown Worcester.

At about 5 p.m., Damon went into an office on Main Street, where he allegedly raped a woman at knifepoint, placing his hands around her throat and stealing her car keys, Worcester police said in a statement. About 10 minutes later, Damon is alleged to have accosted a 21-year-old woman as she left her office on Main Street, and forced her to drive off with him in her blue Subaru Forester, police said.

The attack was reported by the woman’s boyfriend, who was talking on the phone with her, and flagged down a police officer on Grove Street.

At about the same time, another woman approached the officer, to report that she had just been involved in a hit-and-run crash involving a blue Subaru Forester.

About 20 minutes later, police found the car abandoned in a driveway of a home on North Ashland Street. The woman told police Damon had grabbed her throat and sexually assaulted her, the statement said.

A short time later, police received a report of an armed robbery on nearby Denny Street. When officers arrived, an employee told them that Damon had forced himself into the business at about 6 p.m.

Several employees locked themselves inside the bathroom for safety. A male employee confronted Damon, who snatched a gold chain from the man’s neck. The employee spotted Damon holding the knife, and ran outside, police said.

Damon was found crouching down in a corner of the building. Damon complied with a police order to show his hands, but refused to put his hands behind his back, and resisted arrest, police said. He was taken into custody.
