SEREMBAN: Police found a knife on a mattress in the master bedroom of a government agency officer's home, where she was allegedly murdered by her husband yesterday.

"The knife is suspected to be linked to the incident and has been seized for further action and forensic examination," he said when contacted today.

In the incident about 7pm on Thursday, a man reportedly surrendered at the Bandar Baru Salak Tinggi police station in Sepang, claiming that he had killed his wife.
