A MAN was allegedly hacked with a machete and ambulance officers were threatened during a busy Christmas Day for Tweed Police.

Tweed Byron LAC release statements about the incidents on their Facebook page this afternoon.

About 5pm Tweed Police were called to Cox St, Tweed Heads South, where it was reported a man had been stabbed.

"The 23-year-old male victim had received a large laceration to his forearm and was being treated by ambulance officers," the statement said.

"Police will allege that a dispute began between two brothers. The dispute escalated to a point where one of the males struck the other with a machete causing a severe laceration to his forearm.

"The offender was arrested and charged with wound with intent to cause grievous bodily harm. He appeared before a bail court on 26 December and will appear before Tweed Heads Local Court on 6 January 2014."

Meanwhile, just before 4pm Tweed Ambulance NSW officers responded to a call of a man collapsed at Greenway Dr, Tweed Heads South.

"Upon police attending they found two males, aged 20 and 29, (and) a 16-year-old female yelling at each other," the statement said.

"All were to a degree affected by either alcohol or drugs, with a 43-year-old male, the father of the female, sitting on the grass and two ambulance officers in their vehicle.

"It is alleged that whilst Ambulance officers were treating the male, the 29-year-old male and 16-year-old began shouting at the Ambulance officers to provide assistance to the female's father.

"The unconscious male then awoke and threatened the officers, fearing for their safety, they retreated to the ambulance and called for urgent assistance."

Due to alcohol intoxication, or drug ingestion, the situation escalated further.

"The female then climbed onto the bonnet of the Ambulance, yelling at the officers inside, a 29 year old male climbed onto the roof and the 20 year old male laid down in front of the ambulance to prevent it from driving away," the statement said."All four were arrested and taken to Tweed Heads Police Station and charged with obstructing an ambulance officer by an act of violence, malicious damage to property and affray."
