Security for players at the World Twenty20 has been tightened by tournament organisers after a man found a way into the Australia team's quarters at their Colombo hotel and propositioned a player for sex.

The man entered the hotel on Monday and managed to get past security in the foyer of the Cinnamon Grand hotel, before also avoiding the detail assigned to the Australia team's floor. Team security and management immediately informed the ICC of the security breach, while stern words are also understood to have been exchanged with hotel and security staff.

"The man had gone into a player's room offering his services as a male escort," a police officer told the AFP news agency. "The player refused and he barged into another room when the Australians alerted hotel security."

The incident has forced a beefing up of security around team hotels at the World T20, even if the man's intentions did not appear violent, nor linked to any betting or match-fixing scams.

"It was a minor and isolated incident, involving an over-enthusiastic cricket fan, which was reported immediately by the Australia team management to the ICC and relevant authorities," an ICC spokesman said. "The trespasser has been dealt with by the law and the security for the tournament has been briefed and tightened."

A 21-year-old Sri Lankan man, reportedly a past employee of the hotel, was fined Sri Lankan Rupees 1,000 ($8) rupees and handed a one-month suspended jail term after he pleaded guilty on Thursday to a charge of breaking and entering.
