Former Australian swimmer Geoff Huegill and his publicist wife Sara Hill will face court next month after being allegedly caught with cocaine at Sydney's Randwick racecourse.
Police were patrolling the venue on Saturday as part of their regular duties when they were called to a suite in the grandstand by a security guard.
About 5.40pm, police spoke to Huegill and Hill who were allegedly in possession of a small quantity of white powder which police will allege was cocaine.
One racegoer told the Herald that up to 30 police officers swarmed into a number of private suites and stopped people as they were coming out of the bathrooms.
''They were everywhere, outside every door,'' he said.
A racegoer said both uniformed and undercover police were concentrating their search on an exclusive members area called The Stables. ''It was some time in the afternoon with police in uniform and undercover and with several dogs.''
One employee said Huegill was one of the first people police spoke to and said he initially refused to be searched. She said she later saw Huegill and Hill being escorted from the races.
The employee said up to seven police officers were seen talking to Huegill.
''They pulled him out of the suite and asked him why he was about to leave. He looked nervous and refused to be searched and kept asking for a lawyer,'' she said.
She said Huegill was taken from the suite to a private event area for further questioning.
The Herald understands Huegill had spent most of the day with his wife in the Moet suite number 15.
After the news, the vitamin company Swisse said it would not be renewing Huegill's contract when it expires at the end of next month.
''We have not used Geoff in any above-the-line advertising over the past 12 months and we notified Swimming Australia several weeks ago that we would not be renewing our partnership when the contract expired at the end of May,'' Swisse said.
''Although swimming has had a challenging time in recent years, we absolutely commend the organisation for its commitment and hard work in rebuilding the brand and wish them the very best of luck for the future.''
The champion butterflier retired from swimming after the 2004 Athens Olympics but made a well-publicised comeback to the pool during which he shed 40 kilograms and won two Commonwealth gold medals at the 2010 Games.
He retired again in 2012 after he failed to make the team for the 2012 London Olympic Games.
Huegill and Hill, who were married in 2011, were charged with possessing a prohibited drug and will appear in Waverley Local Court on May 14.
The swimmer declined to respond to requests for comment on Monday.
