The 21-year-old man of Tilkaroyidih village told his mother to serve him breakfast at 10 am. He got angry when it was delayed and started beating his mother with a bamboo stick till she died.
After killing his mother, he tried to attack his sister and sister-in-law but they managed to flee and raised an alarm. The neighbours caught him and locked him in a room and informed the police.
The accused has been undergoing treatment under a local doctor, family members said.
