The couple identified as Katie and Chris were shocked to found a naked Irish man in their bed when woman awoke in the bedroom of her Sackville Street home in Sydney on Monday, the Daily Mail reported.
Katie termed the incident as terrifying.
Chris is on one side, I'm in the middle and then our stranger on the end right in with us,' Katie told News Corp, preferring not to disclose her surname.
'So just the sense of someone next to me who shouldn't be there ... He was asleep, I could feel heat.'
Katie woke up her partner who challenged the man. After getting out of bed the intruder, who was naked, picked up his clothes and walked to the rear of the premises.
Katie called up the police while Chris kept the stranger man in the rear yard of the home.
The man climbed in through a kitchen window and wandered around the home until the arrival of police who arrested him.
The man started to convulse when he was placed in the rear of the police vehicle. Ambulance Paramedics were called to treat him for possible drug related health issues.
