Saints ace Mose Masoe’s home was burgled while he played a vital league clash for the club.
A babysitter disturbed the intruder at the 25-year-old prop’s Windle home.
She called police after hearing a noise and seeing the crook walking out of the house before fleeing through the kitchen door.
Masoe was playing for Saints against Warrington at the time of the break-in while his wife was in the stands watching.
The burglar fled with a black and white Michael Kors handbag, which contained a purse, iPad and car keys belonging to the babysitter.
None of the Masoe’s property was taken.
The blockbusting forward was told of the incident in the aftermath of Saints’ September 4 defeat to Warrington and he and his immediately returned to the family’s Bleak Hill Road home.
A Saints spokesman said the club were aware of the incident but declined to comment.
Police described the crook as a white male, aged between 30 and 35, around 5ft 8ins tall and of slim build with mousey brown hair that was shorter on the sides than the top.
He was wearing a tracksuit top which was either dark grey or blue with red markings, dark-coloured sports shorts, and white trainers.
The offender did not speak to the victim or approach her but she was left extremely upset and shaken. The offender left in the direction of the Tesco filling station at Windle traffic lights.
Det Sgt Paul Smith, of St Helens CID, said: “There are no signs of forced entry so we believe the offender has got in through an insecure window or door.
“He has searched several rooms while this young woman was elsewhere in the house and been disturbed after she went to investigate a noise.
“Thankfully, no confrontation has occurred and he has calmly walked out of the back door, around the side of the house and onto the driveaway, having stolen a distinctive black and white designed handbag containing personal items.
“Thursday night was a warm evening and plenty of people will have been in the area while it was still light and who might have seen the offender before or after the burglary.”
