A 30-year old Portuguese national, Pedro Ricardo Eusebio was sentenced for an indefinite period after a four-day trial found him guilty of strangling a woman in the toilets of a West End Bar in London.

On Nov. 25, 2010, at 15:40hrs, Pedro visited the bar in Upper St Martins Lane, WC2 where he was captured on CCTV loitering outside the ladies toilets. A few minutes later, the 22-year-old victim, unknown to the suspect, entered the ladies toilets where she was followed shortly by Pedro.

As the victim came out of the toilet cubicle, Pedro punched her hard in the face and pushed her to the back of the cubicle. He locked the toilet door behind and carried out a "sustained attack" on the victim for over ten minutes, strangling her to the point of unconsciousness, police said. Her injuries indicated that the attack could have been fatal.

He then left the bar and wandered towards Leicester Square. The woman was taken to a central London hospital for treatment and was subsequently discharged.

Officers traced Pedro through CCTV footage which showed him using a cash machine on Charing Cross Road minutes after the attack. He was arrested on Jan. 7, 2011 at his home. He was charged the following day with attempted murder and was remanded in custody to attend court.

"Pedro was waiting for the victim and acted in the knowledge that she would be totally unable to defend herself against him. This sentence reflects the violent and wholly unprovoked nature of the crime and the affect it has had on the victim", said Investigating officer Detective Constable Louise Rochester in a statement.

Judges identified Pedro as a dangerous offender and gave an indeterminate sentence, but was instructed that he would not be considered for parole until he served nine years.
