A 17-year-old girl has allegedly admitted that she strangled her grandmother and with the help of her boyfriend dumped the body on a roadside.
She and her boyfriend were arrested by police in Tak on Tuesday.
The 17-year-old suspect and her boyfriend, 23, were later taken by police to Nakhon Ratchasima, where the crime allegedly occurred.
However, more than 200 angry people had gathered outside the house. Police did not dare to take the suspects out of the vehicle they arrived in for fear they might be attacked.
The pair were arrested on Tuesday afternoon at a road checkpoint in northern Tak province. Police and soldiers noticed two passengers, a young woman and a young man, acting suspiciously.
They learned the girl was the granddaughter of a 62-year-old woman whose body was found on Sunday in a garbage bin dumped on the side of a road in Suphan Buri.
During questioning, the girl allegedly admitted to having strangled her grandmother until she lost consciousness, and then finished the job with a rope she tied tightly around the old woman's neck.
She then phoned her boyfriend, who lived in Tak, asking him for help to dispose of the body.
The suspect said she was stressed staying with her grandmother, who prohibited her from having friends, girls or boys. She said her grandmother had always insisted on taking her with her, wherever she went, since childhood.
According to TV Channel 7 news, police said the victim's husband told police he had borrowed 100,000 baht and given it to his wife.
He believed his granddaughter and her boyfriend used her ATM card to withdraw the 100,000 baht for their own use. This sparked an argument that led to the murder, according to the report.
