Latrell Mitchell and Josh Addo-Carr could face further NRL sanctions after being charged by police with firearms offences.

Just an hour after escaping immediate bans from the NRL following social distancing breaches, NSW Police confirmed the pair would have to face court in August.

The NRL sanctions and police action follows Melbourne winger Addo-Carr uploading footage of himself shooting a gun during a controversial camp on the NSW mid-north coast during the coronavirus pandemic last weekend.

South Sydney fullback Mitchell has also now had his firearms license seized with a number of guns taken by police in Taree.

"Following extensive inquiries, a 22-year-old man attended Taree Police Station about 11.15am today," NSW Police said in a statement.

"He has been issued with a Future Court Attendance Notice for the offence of give firearm to person not authorised by licence/permit.

"His firearms licence was suspended, and a number of firearms were seized by police.

"A 24-year-old man has also been issued with a Future Court Attendance Notice for the offence of use unauthorised firearm."

Addo-Carr and Mitchell were earlier handed a suspended one-game ban by the NRL, which can be activated at any point during the year, for bringing the game into disrepute.

They were also fined $20,000, with another $30,000 suspended, at this stage they are free to play in round three when the NRL returns.

Interim NRL chief executive Andrew Abdo confirmed the initial punishments were only for breaking social distancing rules, and further sanctions could apply for the alleged firearms offences.

"We're not making any judgement on any criminal activity," Abdo said.

"This is based on players acting against a public health order and the fact that this has brought the game into disrepute.

"We will wait before any criminal matter that's investigated by the police and we'll make our judgements then.

"We'll review the findings of the police and once we have that we'll be in a better situation to determine whether or not any further punishment is required."

Both players issued apologies for flouting social distancing rules on Monday, and said the gathering was designed to reconnect with indigenous culture.

Mitchell is South Sydney's highest-profile player, having been brought to the club as a key off-season signing to wear the No.1 jersey.

Just last week the Rabbitohs revealed a clause had been activated to keep Mitchell at the club until the end of 2021.
