The grinning man filmed throttling a schoolboy and punching him 15 times in the corner of a lift before walking away has been arrested and said he did it because he was frustrated at work.

Authorities in the city of Hefei, capital of Anhui Province in East China said the suspect surnamed Liang was detained after a police stake-out outside his residence, although the arrest happened after cops found him at a nearby park.

Liang, who does not live in the Xicheng Shanshuiju Residential District where the boy’s family resides, was not found until several days later.

The Shushan Branch of the Hefei Public Security Bureau confirmed that Liang had been arrested at around 11pm local time on 14th September.

According to the police, Liang has a prior conviction for assault a female victim as well as a minor, leading to a two-year sentence.

He told investigators in a chilling confession that he had spotted the boy alone and followed him into the lift in order to carry out the attack, the cops said.
