The father of six, Nissar Hussain, 49, was attacked by men in Bradford.
He was said to have been hit 13 times with a pickaxe handle and punched and kicked - his kneecap and hand was broken.
Police say that the incident on Tuesday evening is being looked into and are calling the crime a religious hate crime.
However, according to The Times Mr Hussain said that the police have not protected him in previous years.
The British-born nurse converted to Christianity in 1996 but said that problems began in 2008 when his family appeared in a Channel 4 documentary, Holy War, about how Muslim converts are treated.
Following the programme the family relocated, claiming strict Muslims had caused their move.
Mr Hussain claims that he and his family are now prisoners in their own home.
He said the family have had eggs thrown at them, have been attacked in the street and have had their car windscreen smashed multiple times: "The Muslim community are largely decent people but because of the taboo of converting to Christianity we are classed by them as scum and second-class citizens."
Neighbours dispute his claims though and a court case brought by Mr Hussain in March was thrown out after the unemployed man said he was the victim of a religious hate crime.
Saleem Khan, 51, a prominent community member, commented that Mr Hussain's incidents seemed to be personal issues taken up with individuals and that "to blame a whole community for what has happened to him is unfair."
The police said it is investigating the assault and Channel 4 said that it remained in contact with Mr Hussain following the broadcast and that he had not raised any issues at the time, nor approached the broadcaster afterwards.
