A Byron Bay police officer who allegedly tasered a teenage boy and struck him with a baton at least 19 times has been charged with assault following an investigation by the NSW police watchdog.

The Law Enforcement Conduct Commission, in a report presented to parliament in September 2018, found the officer used excessive force when he and three colleagues detained the naked and intoxicated 16-year-old in January of that year.

The commission suggested he could be prosecuted over the incident for assault occasioning actual bodily harm and sacked by the police commissioner.

NSW police on Friday said the serving officer had now been charged.

He was issued a future court attendance notice on Wednesday for common assault and is due to face Byron Bay local court on 2 December.

The LECC in March 2018 held a public hearing to consider whether five officers involved in the boy’s apprehension and subsequent detention engaged in criminal conduct or serious misconduct.

Video of the 16-year-old’s arrest – during which he was capsicum sprayed – was earlier aired on A Current Affair.

The boy, who was on holiday in Byron Bay with his family, told arresting officers “I’m not resisting” in the footage.

He later told hospital staff he’d taken acid but toxicology tests didn’t identify any particular drug, the LECC report states.
