colleagues, neighbors, etc.
This is how Nashar got involved in the bomb plot:
Respected hospital consultant Dr Shakir Al Ani was "approached by Leeds-based Elnashar who said he had a "friend from London" who needed somewhere to stay in the city. There is no suggestion Elnashar knowingly assisted the bombers. Dr Shakir first met Elnashar at the Leeds Grand mosque close to Alexandra Grove four years ago.
The two became friends and Dr Shakir rented him one of several properties he owns in St John's Terrace, close to the mosque. (...)
"There was someone coming from London who needed somewhere to stay so I gave Magdy the keys for him about a month ago. I did not take the other man's full name and I never met him. But I spoke to him on the phone. He had a British accent, it was not a distinct accent but he was fluent.
"He told me he wanted to get rid of some of the furniture because he needed the space, that his wife was coming and he wanted to 'do it up'. I didn't think it was a problem but explained it wasn't my property."

He must have had a convincing story of how he met Hussain: now both Egyptian and British authorities seem to believe him.
