Police in Malaysia are trying to trace a former postman after finding more than 20,000 undelivered letters at a room he once rented.

It is thought the 27-year-old worker, who has not been named, has been hoarding mail for years.
The man had worked for Pos Malaysia for almost eight years until being sacked in March for absenteeism.
The haul was uncovered after a security guard found 200 undelivered letters in an apartment in Kuala Lumpur.
Further investigations led to a room that was previously occupied by the missing postman, where authorities found a further 21,000 items - bills, bank statements, postcards and magazines.
There were even registered letters and an express delivery item which had never quite managed to live up to its billing, having been sent four years ago.
However, the intended recipients will not be seeing their letters anytime soon.
Their letters cannot be delivered until police decide they no longer need them for their investigations.
The head of Malaysia's postal service says staff will be more closely monitored in future.
Earlier this year, a British former postman was found to have kept more than 3,000 undelivered letters and parcels in his home.
