Ben Cousins in hospital after allegedly being caught at SAS barracks

Former West Coast Eagles captain Ben Cousins is reportedly at a mental health facility after being caught behind the secure fences of an SAS base.

The ex-AFL star was apprehended at the Campbell Barracks in Swanbourne about 11pm on Saturday.

It is understood he is currently being assessed in the mental health ward at Sir Charles Gairdner Hospital.

Last week, the premiership player was charged after allegedly being caught driving recklessly and refusing to give a breath test.

Police said at the time that a 36-year-old Bicton man was arrested after allegedly driving erratically and not stopping when requested by police.

The Brownlow medallist is due to appear in the Fremantle Magistrates Court on April 8.

Cousins fell from grace following a string of off-field incidents and substance abuse problems.

The father-of-two was suspended for one year by the AFL in 2007 for bringing the game into disrepute before making a comeback with Richmond. He retired in 2010.
