A stalker who threatened Chester Bennington's wife and electronically tracked his movements has been sent to prison.

Devon Townsend must serve two years behind bars after she was convicted of numerous offences against the Linkin Park singer.

Townsend, a computer expert who worked for the government in a national security laboratory in New Mexico, used a computer to stalk the star.

In court, she admitted obtaining family photos, accessing email and voicemail and also threatening Bennington's wife Talinda.

Townsend, who also accessed a host of information about his movements with Linkin Park and their record label, will undergo mental health treatment in jail.
