These shocking scenes show a bloodied 13-year-old boy being violently dragged back into a Tesco store by security staff - after allegedly being caught stealing SWEETS. Witnesses say the sleight youngster was attempting to flee the shop without paying when a member of the public grabbed him and pulled him back. But as a struggle broke out with a security guard, the fracas seemingly turned violent. The boy was filmed being dragged backwards with his t-shirt pulled over his head and was left bloodied by the ordeal. Devon and Cornwall Police said they were investigating the incident, which occurred in Exeter, Devon, on Sunday, and said it was sparked by the theft of 'low value confectionery'.
