An 18-year-old man arrested earlier this month for operating a motor vehicle with a suspended license is facing more legal problems after he allegedly harassed a local police officer set to testify against him in court.

Police have charged Paul Braster of Salem with harassment and witness tampering after he allegedly called Sgt. Mike Wagner 20 to 30 times in reference to his legal troubles. Though police said Braster was repeatedly warned to stop, he allegedly used false pretenses to contact Wagner again and asked that the officer not testify against him.

Braster had been out on bail for his prior arrest which came after officers recognized him operating a vehicle with no license plates along North Main Street on March 19. Police said Braster ignored officers and proceeded to drive home on Pawtucket Lane where he was taken into custody.

While being processed, police said Braster made threats against police officers, including threatening to drive his vehicle through the front of the station after he was released.

Braster faces charges of disobeying a police officer, failure to display plates, operating after a suspension and criminal threatening stemming from that arrest.
