A 31-year-old man was killed and his 27-year-old girlfriend critically injured after a grenade exploded inside a home in Sisaket province on the night of 4 June 2026. The blast occurred at a single-storey concrete house in Ban Chan Daeng, Bang Don subdistrict, Khun Han district, leaving windows shattered and causing severe injuries to the woman, who remains in a serious condition. Get today's headlines by email Police identified the dead man as Udomsak “Janjao”, 31. The injured woman, Thanita “Kat”, 27, was initially taken to Khun Han Hospital before being transferred to Sisaket Hospital. Medical staff operated on her skull after grenade fragments became lodged inside it and into parts of her brain. The explosion happened at around 8.50pm while the couple were inside a bedroom. Thanita’s mother was watching television elsewhere in the house when she heard the pair arguing, followed by a loud explosion. When she tried to reach them, she was unable to open the bedroom door and later saw the aftermath through a window before collapsing unconscious. A relative living next door said the blast was so loud that she initially thought it was thunder or artillery fire from across the nearby Thai-Cambodian border. She said the couple had a history of repeatedly separating and reconciling and alleged that Udomsak had previously been involved with drugs. She added the source of the grenade were unknown to the family. Thanita’s mother said she had no knowledge of any grenade being kept at the house and was unaware of what led to the incident. Her main concern, she said, was her daughter’s survival. Police later established that Udomsak and Thanita had been in a relationship before Udomsak served a prison sentence in a drugs case. After his release around two years ago, the couple allegedly experienced ongoing domestic problems linked to his jealousy and suspicions. Investigators believe the explosion occurred during an argument inside the bedroom. Udomsak was found dead on the bed from blast injuries, while Thanita suffered critical wounds. Police said the device used was a hand grenade, known locally as a “look klieng”, which Udomsak had reportedly obtained from a friend. Reporters also found a social media post on Udomsak’s account before the blast. It included a photograph of himself and a message suggesting he wanted to find out whether something was real or fake and indicating that another person would “go with me”. Amarin reported that authorities continue to investigate the source of the grenade and the circumstances surrounding the explosion. Thanita remains in a coma in ICU.
