SINGAPORE - A man trespassed into a function room of a hotel and stole 13,268 euros ($20,253) worth of 2016 Formula 1 Singapore Grand Prix passes.

Chen Jianyi, 34, was on Friday (Sept 22) jailed for one month for the theft of two United Parcel Service (UPS) F1 Paddock Club passes, among other items, at the function room of Conrad Centennial hotel on Sept 18, 2016.

He was fined the maximum of $1,500 for criminal trespass.

The court heard that Just Marketing's event manager Katherine Elizabeth Jackson had been engaged by UPS to handle marketing for the 2016 F1 Singapore Grand Prix.

She used the function rooms on the second floor of the hotel to store items related to the Grand Prix, which was ongoing.

Nobody other than those authorised by Just Marketing was supposed to enter.

On Sept 18 last year, Chen went to the second floor of Conrad Centennial and saw a bundle of passes and lanyards inside the unlocked function room. He stole some of the passes and put the items into his jeans pocket.

Ms Jackson discovered that the items were missing and reported the loss to the organisers of the 2016 F1 Grand Prix.

On Sept 18 last year, Chen and his friend used the two Paddock Club passes to enter the restricted area near the junction of Temasek Avenue and Raffles Boulevard.

The two men wandered around for a while before entering the Ferrari garage where they were stopped and detained by F1 Grand Prix staff.

No restitution has been made.

Chen, who had five other charges taken into consideration, could have been jailed for up to seven years and fined for theft. The maximum penalty for criminal trespass is three months' jail and a $1,500 fine.
