A mother in South Carolina (US) called police on her son this week after finding porn playing on her living room TV.

According to the Spartanburg County Sheriff’s Office, deputies were dispatched to a residence Tuesday afternoon after a distraught mom called 911.

“She stated that when she entered the residence, her 15-year-old son was in his bedroom,” reads the police report. “[Her] daughter turned on the TV and porn was revealed.

According to the report, the 40-year-old mum “immediately turned off the TV” and ushered her 2-year-old daughter out of the room, before calling the police on her son.

When the police arrived, the mother said she had several problems with her son’s behaviour recently.

“[The mum] requested that a report be done to document … her son’s behaviour and due to her daughter being exposed to porn,” the police report reads.

According to Lt. Kevin Bobo, the sheriff’s office did not make an arrest or issue a citation.

“I don’t know of any South Carolina law that was broken,” Bobo told HuffPost on Thursday.

However, the teen’s mother did complete “a voluntary statement” detailing the incident, according to the police report.

“Is it unusual for a momma to call the police on teenagers looking at porn? Yeah, it is,” Bobo said.
