Ben Te'o will not be charged in relation to an assault allegation stemming from an incident in April.

The South Sydney forward had been accused of assaulting Brisbane woman Katie Lewis, who went public with her claims before lodging an official complaint with police.

Katie Lewis claimed to have been assaulted by NRL player Ben Te'o.

The allegation hung over Te'o's head for the duration of the Origin series but he was informed on Thursday no action would be taken by Queensland police, who have concluded their investigation.

Te'o has also been cleared by the NRL's integrity unit, which conducted investigations independently of the police.
