A man whose online death threats to ‘Jihadis’ on Twitter led to armed police swarming on his house has no regrets and would do it again.

The man, whose identity the Croydon Guardian has withheld for his own safety, posted several tweets on the social networking website after two gunmen stormed the offices of the Charlie Hebdo magazine in Paris murdering 12 people.

His messages invited 'jihadis' to "Come and get me" and published his address.

The 56-year-old, who suffers from chronic obstructive pulmonary disease and Crohn’s disease, was then surprised when he opened his door in Coulsdon, a short time later to find police officers with guns pointed at his home.

He said: "The police seemed to think that they are a branch of social services.

"One of them was holding up a riot shield. I’m so ill I could not fight my way out of a paper bag.

"I invited them in and offered them a cup of tea and their main concern was for my welfare."

An ambulance was also called and he was checked over but he refused to go to hospital.

He said he had made remarks about Islam to officers during police interviews but said he has never been charged over his views.

He added: "All the police I have encountered were very nice and friendly.

"I’m staying on Twitter but maybe I should be more circumspect.

"I’m still going to continue to say what I think, I do not have long to live so I don’t really care."

Police checked over his air rifle and left his home when they were satisfied it could not be used to fire live ammunition.

He has since deleted tweets saying where he lived.

A Metropolitan Police spokesman said: "Police were called, with reports of concern for the welfare of a man, following recent tweets linked to an address in Coulsdon.

"London Ambulance Service also attended and the occupant was found safe and well at the address.

"He was spoken to by officers and given advice about information he was tweeting."

"There were no offences identified and no arrests."
