UFC star Conor McGregor was taken into custody in Corsica for alleged indecent exposure and attempted sexual assault - but 'vigorously' denies the explosive accusations against him. 

The former two-weight UFC world champion was arrested Thursday for 'acts that could be described as attempted sexual assault and sexual exhibition', prosecutors say.  

A representative for McGregor shot down the allegations, telling TMZ: 'Conor McGregor vigorously denies any accusations of misconduct. He has been interviewed and released.' 

The Irishman, who is no stranger to controversy, has been based on the French island over recent weeks to prepare for a 110mile voyage to raise awareness for water safety. He had been due to set off today with Princess Charlene of Monaco, but has been forced to withdraw.
