England centre Manu Tuilagi has been formally warned by police for disorderly behaviour after jumping from a ferry in Auckland.
A Rugby Football Union (RFU) source confirmed that Tuilagi was detained by police after swimming a short distance to pier three at the ferry terminal.
The RFU would not comment on whether alcohol was involved but did say the player was unharmed.
The England team are due to leave for the UK later on Monday.
The Samoa-born Leicester Tigers player jumped off the Fullers ferry Superflyte on its arrival from Waiheke Island, with the defeated England team on board just before 1900 local time (0700 BST) on Sunday.
After being warned at Auckland Central police station, he was then released to the England team management.
England were knocked out of the tournament by France in the quarter-final earlier on Saturday.
Earlier this month, the International Rugby Board fined Tuilagi £4,800 for wearing an unapproved mouthguard carrying the name of a sponsor.
