The officer, Juan Moreno, said he coincided with the defendant in the Sueño bar just hours before being stabbed. He also admitted he was on duty at the time, which he had previously denied.

  The sergeant was stabbed in the leg outside the Pachanka bar in the early hours of 22nd June by a local Argentine businessman.

  In his statement he also confirmed he had not heard the threatening comments made by the defendant, and said he was told of them by a fellow officer who was with him at the time. He said the man asked him to step outside the bar. Moments later he was stabbed in the leg. He said that although he did not see the defendant actually stabbing him, there was no one else in the vicinity.

  His statements contradict some witness reports which said the defendant was hit several times by the officers before being dragged out onto the street.

The trial continues.
