MANCHESTER, Conn. (WTNH) — What started as an investigation into an alleged shoplifting suspect, turned into a medical emergency.

Manchester police say a 44-year-old man slashed his throat with a knife while he was being questioned by Walmart security on Wednesday afternoon. Police were called to the Buckland Hills Walmart around 1:30 p.m. for a report that a possible shoplifting suspect had sustained serious self-inflicted wounds while being questioned by store security.

Police say a 44-year-old male suspect allegedly switched the price tag on a vacuum cleaner and tried to buy it at the lower price. Store security approached the man and brought him into their security office to get his information. Police say while security was speaking with the suspect, he pulled a knife out of his pocket and slashed his neck. He sustained a significant, and potentially life-threatening injury and was taken to Hartford Hospital.

There is no update on his medical condition. Police have not released his identity as they are still trying to notify family members.
