Earlier today, it emerged that the 24-year-old actor had been charged by police after being taken into custody at the weekend.
More details of the incident have now emerged in the Australian media. Reports suggest that Lasance was arrested at Sydney nightclub Kit and Kaboodle on Saturday after police with sniffer dogs raided the venue. It has been alleged that officers discovered the soap star had a small bag of white powder in his possession after approaching him in the men's bathroom.
The police raid was part of Operation Unite, a national campaign which targets anti-social behaviour in Australia.
A New South Wales police spokesman said: "The 24-year-old man was allegedly caught during a drug detection dog operation at the club, as part of Operation Unite, just after 11pm on Saturday."
It is thought that Lasance, who plays Summer Bay's Aden Jefferies, had been partying with Home and Away cast and crew members at the club shortly before his arrest.
A spokesman for the Seven Network, which broadcasts Home and Away in Australia, insisted that the festive party had not been "sanctioned" by the channel.
Meanwhile, Lasance's manager David Sheridan said that his client was "not commenting" on the matter.
