A Boston Public Schools custodian has been charged with assaulting three school employees, allegedly attacking them while saying, “You all cost me money.”

Gregory Watford, 46, of Brockton, is accused of assaulting the Mildred Avenue School employees — seriously injuring his former colleagues.

Watford has been charged with assault and battery on a person over 60, and three counts of assault and battery causing serious bodily injury.

“This violent incident is particularly disturbing because it happened on the grounds of a public school, which is both a workplace and a safety zone for students,” Suffolk DA Kevin Hayden said in a statement.

Boston cops responded to the Mildred Avenue School for an assault on Oct. 10 at about 10:47 a.m.

Police spoke to the victims — two school custodians and one safety officer — who reported being assaulted by their former colleague, later identified as Watford.

The school custodians told police that they were in the front of the school raking leaves when Watford approached them in an aggressive manner. They said Watford began attacking them while saying, “You all cost me money.”

Watford earned $82,916 last year, according to Herald and city payroll data, including $9,999 in overtime.

Watford allegedly punched the first victim in the head, causing him to fall to the ground and resulting in a broken ankle and leg.

Watford is then accused of punching the second victim in the head and throwing him to the ground, resulting in a fractured jaw.

The school’s safety officer came outside to intervene. Watford then tried to get inside the school building, but the safety officer blocked the doorway.

Watson then allegedly swung at her, hitting her hand and knocking her phone to the ground. Watford then swung the door open, striking the officer in the left shoulder, resulting in a fractured clavicle.

“I wish the three victims a thorough recovery and our office will provide all the support they require as this case moves forward,” Hayden said.

Watford fled the scene before police arrived. A warrant was issued for his arrest.
