Sexual assault charges against former Connacht player Mils Muliaina have been dropped.

The crown prosecutor confirmed in a latter to the former All Blacks lawyers that the charges had been dropped due to a lack of evidence.

Muliaina, 35, was alleged to have touched a woman on the bottom over her trousers in a Cardiff nightclub the night that Connacht played a Pro12 away game against Cardiff Blues on 7 March.

The New Zealander was questioned by police after Connacht's clash with Gloucester in in the Challenge Cup in April and he was charged in July.
