Former Terminator star Edward Furlong faces four years behind bars after allegedly assaulting his ex-girlfriend, actress Monica Keena. The former child star has been charged with felony dissuading a witness by force or threat and felony vandalism following claims he damaged his former lover's laptop and photo equipment during a dispute at her home last month (May13). Furlong is also accused of threatening her if she called the police, according to TMZ.com. The actor was arrested following the altercation on suspicion of violating a protective order she had obtained against him. He has also been charged with disobeying a domestic restraining order - a misdemeanour - and has been ordered to return to court on 1 July (13). At press time Furlong was still behind bars - he was initially released on 18 May (13), but returned to jail on 10 June (13) after a Los Angeles judge ruled his bail was too low. It has been a tough week for stars who have played John Connor in the Terminator movies - Nick Stahl has been placed on an involuntary psychiatric hold after he was hospitalised in Los Angeles. The Terminator 3: Rise of the Machines star, who has long struggled with drugs and alcohol abuse, was admitted to a medical centre in the early hours of Tuesday (18Jun13).
