A woman who was found in toilets at Etihad Stadium two days after the ground was last used has been reunited with her family.

The 57-year-old woman was admitted to Sunshine Hospital yesterday after she was found by stadium staff in a confused state.

It is believed that the woman had spent two days locked inside the ground following the AFL match between Geelong and Richmond on Sunday.

A spokeswoman for Western Health said the woman, who is in a stable condition, had today been transferred to another hospital. The spokeswoman said the woman's family had made contact with her.

This afternoon Etihad Stadium management released a statement saying the woman's son and other family members contacted them late yesterday after their mother had been missing for "a number of days".

"Stadium CEO, Ian Collins AM said it seemed that after being absent from her family for a number of days, she had now been reunited with her son and other family members," the statement said.

A spokesman for Etihad would not give any further details about how the woman came to be locked inside the stadium. "We will not elaborate any further," communications advisor Bill Lane said.
