Mid Valley Megamall has apologised over a rat incident at a branch of Komugi within its premises and has unveiled a slew of pest control measures.

"With regards to the incident in Komugi on Oct 23, the Mid Valley Megamall management would like to apologise to our customers for the distressing experience," it said in a Facebook post today.

The management said the bakery has been shut down for thorough cleaning and review of operational procedures but the mall's own procedures are also being reviewed.
