Stuart Boyd Mills, a British national, was sentenced to one week's jail on September 23 after he was caught on video punching a security guard at Roxy Square in the face on April 4.

According to Channel NewsAsia, Mills, who is a Singaporean permanent resident, pleaded guilty to one charge of voluntarily causing hurt.

A second charge of using abusive words against duty security supervisor Andrew Lim was also taken into consideration for his sentencing.

Mills, 47, was charged in court 20 days after the incident happened.

Surrendered himself after punching security guard

Mills had three bottles of liquor prior to the incident.

He met with Lim past midnight when he was trying to locate the exit of the mall.

As the security guard explained the location of the exits, Mills became aggressive, and another officer was asked to record the incident on the phone.

Mills, as seen in the video, did the same, trailing Lim and trying to trip the security guard.

He would then punch Lim, who fell to the ground.

Lim called the police, and Mills was later detained after returning back to Roxy Square to apologise for the incident.

Lim was injured with a swollen eye, sprained neck and broken glasses.

Mills has since paid S$2,000 in compensation to Lim.

Since the incident, Mills, who owns an ad agency, had apparently received abuse and hate mail through his phone and letters to his address.

His lawyer said that he also has been diagnosed with a major depressive disorder, but has been seeking medical help and measures to reform his behaviour.

Mills could have been jailed for up to 2 years, fined a maximum of S$5,000 or both for voluntarily causing hurt.
