Mohammad Asghar, a British national, was arrested in Pakistan in 2010 after writing letters to people - including a police officer, claiming that he was a prophet, Dawn.com reported.
Insulting the Prophet Mohammed can carry the death penalty in Pakistan.
Asghar was arrested under section 295-C of the PPC, the newspaper reported, which reads:
“Whoever by words, either spoken or written, or by visible representation or by any imputation, innuendo, or insinuation, directly or indirectly, defiles the sacred name of the Holy Prophet Mohammed .... shall be punished with death or imprisonment for life, and shall also be liable to fine.”
