Man arrested after attacking police

A Dorchester man has been charged following an incident on Saturday.

Boston police say they were called to 238 Warren Street in Roxbury just after 4:30 a.m. for a call from a person with a knife. Additional details were provided including a description of the suspect who allegedly stole the moped.

When they arrived, they were met by the victim who told them about the stolen moped and that he had tracked it to the address. When he went to retrieve it, the suspect; identified as Michael Williams, 38, of Dorchester, allegedly threatened him with a knife.

After a brief search of the area, the suspect was found sleeping in a box truck. When officers instructed Williams to exit the truck, he pushed one of the officers and struggled with him.

Williams was eventually arrested and a knife was found from his right pants pocket.

He was charged with two counts of assault and battery with a dangerous weapon, receiving stolen property over $1,200 and intimidating a witness.

Police also determined that the suspect had three outstanding arrest warrants.

He is expected to be arraigned in Dorchester District Court on Monday.
