Walker and Gray allegedly involved in Thailand incident

Aaron Gray and Dylan Walker have again landed themselves in hot water after allegedly being involved in an incident in Thailand.

A man reportedly complained to the NRL Integrity Unit about the players after his son was arrested in Phuket, Thailand.

Both players were reportedly at the same venue as the man who was arrested.

Gray and Walker are currently being investigated by their clubs South Sydney and Manly.

An NRL spokesman confirmed the integrity unit was aware of the incident and making enquiries.

Neither club was available for comment on Wednesday night.

The two players have history together after almost losing their lives last year due to a prescription drug overdose.

They were rushed to hospital after being found vomiting by a mutual friend at Gray's Sydney apartment in the early hours of the morning.

Both apologised for the incident when they eventually recovered.

"We'd like to apologise to all our family and friends for the last few days. We know it hasn't been easy," Gray, 21, said.

"We've learnt from our mistakes and we hope that everyone can learn from our lessons, not only rugby league players, but people in general.

"Just take prescription medication as it is on the prescription box."

A similarly contrite Walker admitted he and his teammate had erred.

"I'd like to say sorry to our friends and family for the mistake we have made," Walker, 20, said.

"It's a lesson we have learned and we hope everyone can take a lesson out of this."
