A teenager from Batu Caves, believed to be mentally unstable, caused a stir when he showed up naked and challenged his martial arts teacher to a fight.
Berita Harian reported that the 19-year-old went to his teacher's house in Kampung Laksamana in Gombak at 7am three days ago, apparently upset that he could not complete his silat training.
The student's shouts and threats to set fire to the teacher's house caught the attention of neighbours, who helped restrain him.
The entire incident was recorded on a closed-circuit television camera (CCTV).
Gombak OCPD Asst Comm Ali Ahmad said the boy tried to escape by running into a neighbour's house and holding on to a 58-year-old woman inside. Luckily, he did not hurt the woman and was later handed over to the police.
