DAP chairperson Karpal Singh has received a handwritten death threat and two live bullets in his mailbox.

According to the veteran politician, the letter originated from Ipoh, the capital of Perak, whose Sultan, Karpal had wanted to sue over the ongoing political crisis.

Karpal said the letter was sent to his house in Penang.

Among others, the letter warned the Bukit Gelugor parliamentarian and renowned lawyer not to challenge the Malays and the royalty.

The envelope also contained a picture of Perak ruler Sultan Azlan Shah.

On Feb 6, Karpal had threatened to sue the Sultan over the appointment of a Barisan Nasional state rep as the new Perak menteri besar.

However, he did not follow through with his threat.

BN leaders and their allies have so far lodged more than 100 police reports against Karpal over the matter.
