CCTV footage shows the suspicious shopper, wearing leggings and a hoodie, have a quick look around before squatting and pulling down her bottoms
This disturbing video shows the vile moment a woman took a sneaky number two down a supermarket aisle - then carried on shopping.
Disgusted staff at B&M Bargains found a pile of poo on the floor covered up with over £40 worth of baby clothes.
At first they believed the culprit to be a dog or a young child, but security guards of the cheap goods shopping chain were stunned when they pulled up the CCTV cameras.
In the footage, obtained by the Mirror, a shifty-looking female shopper in her mid-30s, wearing leggings and a hoodie, is seen having a quick look around.
She then moves out of the way of the security cameras, making sure nobody is watching, before squatting, pulling down her bottoms and defecating on the floor.
And remarkably, she then stands up, pulls up her pants and carries on with her shopping - as if nothing had happened.
Several staff at the store slammed the act as "disgusting" and "filthy" on social media.
It is believed to have happened in the Southport store last month.
B&M Bargains refused to comment on the incident when contacted by the Mirror.
