A delivery driver who stole crabs from his employer was jailed for four weeks on Wednesday.

Elvin Koh Sing Kiat, 37, pleaded guilty to three charges of stealing $712 worth of crabs with his colleague, Lim Chee Beng, 42, at Eng Lee Seafood Trading at Sungei Tengah, Agrotechnology Park, between Aug 19 and Sept 1 last year.

Twelve other similar charges involving $440 were considered during his sentencing.

A district court heard that Koh was entrusted with the key to a storeroom where seafood was stored.

Sometime in end-July last year, Lim, then a driver, and Koh hatched a plan to steal crabs from the company and re-sell them to the company's customers.

Each time they wanted to steal the crabs, Koh would pack additional crabs into the delivery lorry driven by Lim, who would sell them on his rounds and share the proceeds equally with Koh.

Lim, who had admitted to theft and other offences including harassment, was given 25 months' jail and three strokes of the cane last month.

Koh's lawyer Michael Chia said his client had made full restitution of $1,152 and was still working for the company, which wrote a letter pleading to the court for leniency.

Koh could have been jailed for up to three years and/or fined on each charge.
