Authorities say a Massachusetts trolley driver paid a man $2,000 to attack him while wearing a Halloween mask so the driver could fraudulently collect workers' compensation and disability insurance.

A Suffolk County grand jury indicted Thomas Lucey on charges of insurance fraud, workers' compensation fraud, misleading a police investigation and perjury.

Prosecutors say the Massachusetts Bay Transportation Authority driver reported the man pulled him out of a trolley shortly after midnight on Oct. 30, 2016, and punched him repeatedly. The attacker wore a mask and carried a plastic pumpkin.

Authorities say they got fingerprints off the pumpkin, which was left behind, and found the man that way.

He said Lucey paid him for the phony attack.
