It was clear, police said, that Jaidyn Barber was himself severely affected by drugs or alcohol - or even both - when he lashed out.

The 21-year-old's violent behaviour has been slammed by Albury Local Court magistrate Rodney Brender.

Mr Brender said police should not be subjected to such antics where they "are just trying to do their job".

Barber pleaded guilty to two counts of assaulting police and represented himself in court.

"I would just like to apologise to the police officers for what I have done," he said.

Barber said his only excuse was that he was extremely worried about his friend who had passed out.

The court was told how police went to Beer Deluxe in Kiewa Street, Albury, on June 20 just before 12.30am.

An ambulance had been called as there were reports that a man inside the hotel had possibly suffered a drug overdose.

The officer waited outside for the paramedics to arrive.

One of the paramedics was trying to get the gurney out of the back of the ambulance when Barber ran towards them and opened the side door.

"The accused was warned by the ambulance officer and by the (policeman) to get away from the ambulance," police said.

"The accused was well-affected by alcohol and stated he was concerned for his friend's welfare."

In response, Barber was told his friend would be OK and that he needed to let the paramedics do their job.

They went inside the hotel then brought the man back out on the gurney. But Barber had not moved away.

Barber's response to being told to leave was to use both hands to shove one of the police officers in the chest.

After being handcuffed, he tried to headbutt one of the police though the officer ducked and took the impact to his left shoulder.

Barber was convicted and placed on a 12-month community corrections order.

He must complete 100 hours of unpaid work.
