Former NZ Warriors centre Anthony Gelling has been suspended by the Warrington Wolves, after his arrest on suspicion of wounding with intent.
Cheshire Police received a report of assault at an address in Widnes on Sunday (NZ time), which led to a 29-year-old man being arrested and released on conditional bail.
A police statement said a man had been "arrested on suspicion of wounding with intent".
"He was questioned by detectives and released on conditional bail, and enquiries into the assault remain ongoing."
The Auckland-born star is in his first season with Wolves, after transferring from Widnes Vikings last year.
Gelling has featured in both Wolves' Super League matches so far this season and is now unavailable for selection, leaving his career in doubt.
The club said Gelling was the subject of a club investigation into his "conduct away from the club" and he was "fully supportive of the investigation".
"The club and player will be making no further comment at this time," its statement added.
Gelling courted controversy early in his career, when he was sacked by Sydney Roosters for defecating in a hotel room.
After five years playing for the Wigan Warriors, he returned to New Zealand, after his girlfriend was involved in a car crash.
Gelling played seven games for the New Zealand Warriors in 2018, scoring two tries, before returning to England to play for Widnes in the 2019 Championship.
He also helped the Cook Islands qualify for the 2021 Rugby League World Cup.
