Three men, including one from Watertown who was arrested in Waltham for distributing drugs in May 2008, were arraigned Friday in connection with a disturbance in the Cambridge Jail, according to Middlesex District Attorney Gerry Leone.
Justin Deprospo, 25, of Watertown, David Agnetta, 31, and Stephen Andrade, 31, were on charges of malicious destruction of property over $250 and assault with a dangerous weapon. Agnetta and Andrade were also arraigned on charges of assault and battery on a correctional officer. Deprospo was arraigned on a charge of assault on a correctional officer.
Agnetta was ordered held on $10,000 cash bail. Andrade was ordered held on $1,000 cash bail. Deprospo is currently being held on another case.
Deprospo was being held in the jail for a previous charge of possession with intent to distribute class E drugs, subsequent offense.
Their next court date is Feb. 25 for a pre-trial conference.
The three defendants were indicted by a Middlesex Superior Court Grand Jury on Jan. 21.
According to authorities, at approximately 12:10 p.m. on July 5, 2009, The Middlesex County Jail, 40 Thorndike St., Cambridge, went into an initiated lockdown due to an ongoing inmate disturbance. The defendants, located in the jail's 18th tier, were observed vandalizing the jail and smashing sprinkler heads causing water, flowing at rate of 25-35 gallons per minute, to flood the floor within minutes. The flooding eventually reached 18 floors down to the building entrance, eliminating the use of all elevators and requiring the power to the building to be shut off.
Additionally, Agnetta allegedly attacked a correctional officer on duty with a 6-foot wooden bench. Deprospo is alleged to have assaulted two correctional officers with a wooden plank. Andrade is alleged to have thrown a glass object at another correctional officer, causing it to shatter on the officer's head, shoulders and back.
Cambridge Fire Department, Courthouse and Middlesex emergency personnel responded and the detainees were secured in cells. The vandalism that occurred caused the 18th floor of the jail to be uninhabitable and an evacuation of effected detainees ensued.
As a result of the Cambridge jail disturbance, the clean up and replacement of vandalized equipment including lighting, ceiling fixtures, computers and inmate property, cost over $250,000.
In May 2008, Waltham Police found Matthew Mann, of Manchester N.H., unconscious with a pile of burnt dollar bills on the floor in a stairway at the Westin Hotel on Third Avenue. Police later found Deprospo and a large amount of drugs in Mann's hotel room.
During a taped conversation with an undercover agent, DeProspo revealed "he had been involved in the steroid business for over four years and has two to three different steroid sources and tons of customers," according to court documents.
