"Those men I had never seen them in the park before, and I said to them "what are you doing here, why are you doing to this to the kids?"

"He said are you a Muslim or a Catholic, and I said it doesn't matter, I know about Islam, and it's not what you're doing."

Following the dispute Ms Gasparri went to Barking Police station where she claims police officers told her the photos and information she provided was "now with Scotland Yard".

However, she said that nothing seemed to have been done about him and that she was "furious" that the warning signs may have been ignored.

"They [the police] were very concerned about it," she added. "They told me to leave the photos for my own safety, but then I heard nothing."

Whilst being interviewed by reporters, Ms Gasparri went on to confront a Polish woman called Romana, who she accused of tipping off the suspected attacker about her police interview in 2015.

Erica said that she had told Romana about the police interview who had then informed him that police may be aware of his activities.
