The latest incident involved a warehouse in the Kota Kinabalu Industrial Park and a factory along the Jalan Tuaran By-pass here.
In the first incident, a businessman identified only as Chua, claimed to have lost valuables and cash worth about RM15,000 to burglars who broke into his two-storey noodle warehouse.
"I opened for business yesterday only to find my warehouse has been ransacked," he claimed.
He claimed that the thieves even took the time to have a feast in the warehouse because there were empty canned food scattered around the premises as well as peels of oranges strewn on the ground.
"I suspect that the culprits might have gained access through the roof because there is a huge hole on the ceiling which was not there before," he said, adding that the culprits might have gone out through the window on the second floor.
It was learnt that he lost RM3,000, computers and a 32 -inch LCD television among others.
In the second incident, a zinc processing factory along Jalan Tuaran By-pass was also broken into.
An employee who stopped by at the premises made the discovery at about 12pm on Monday.
It was learnt that the premises was closed for the holidays and was supposed to start business on Tuesday.
The culprits were believed to have entered the premises through a window on the first floor which leads to the administration office.
It was believed that valuables and cash worth about RM200,000 were missing from the premises.
