Baling police chief Brandon Richard Joe said police were alerted to the incident at around 7pm yesterday after the 21-year-old suspect ran amok, Bernama reported.
The deceased had stab wounds at the back of her body while her mother had stab wounds at the back of her neck.
Brandon said the suspect had an intellectual disability and was detained by members of the public before being brought to the cops, who then arrested him.
“The suspect has no criminal record and admitted to stabbing his grandmother and great-grandmother at the scene,” he said.
Police will apply to remand the suspect today to assist in their investigations for murder and attempted murder.
