A man who went on a drunken rampage at a hotel in April and rained blows on a hotel manager was sentenced to jail and a fine yesterday.

New Zealand national Davis Brian Uerata, 44, who is in the construction industry and works in Thailand, was sentenced to four weeks' jail and fined $1,600 after admitting to six of 15 charges. He could not pay the fine and will serve another eight days' jail in default.

While staying at the Peninsula Excelsior Hotel in Coleman Street, Uerata became agitated and started hurling profanities at front-desk supervisor Melvin Mahendiran just before 4am on April 28 when he was asked for his name and room number.

When duty manager Herry Wan Zhee Kuang, 50, tried to talk to an intoxicated Uerata, he was scolded.

Uerata became more agitated and aggressive when Mr Wan told a security officer to call the police.

The hotel's closed-circuit television camera showed Uerata jump over the front-desk counter and lunge towards Mr Wan. He then grabbed Mr Wan by the neck and pushed him to the floor.

When Mr Mahendiran and security officers tried to pull him back, Uerata overpowered them and punched Mr Wan several times in the face, causing bleeding. As Mr Mahendiran tried to stop Uerata from attacking the victim further, Uerata pushed him on the chest.

Uerata also punched a glass display stand, valued at $350, causing it to fall to the ground and break.

CCTV footage further showed Uerata pushing and punching Mr Wan at the lobby lounge. The victim suffered a contusion and was given five days' medical leave.

Deputy Public Prosecutor Huang Jiahui said that when the police arrived, Uerata assumed a boxing stance and uttered abusive words at the officers. He refused to answer questions and asked the police to arrest him. He continued to behave belligerently and officers tasered him before placing him under arrest for disorderly behaviour.

His blood sample was found to contain 92mg of ethanol per 100ml of blood, 12mg more than the legal limit for drink driving. He was represented by Mr Amarjit Singh. His sentence was backdated to Oct 12.
