Four people have been robbed by armed thugs just days around Christmas.
Two were violently robbed just three days before Christmas, on December 22nd.
Another man received a slash wound when one tried to steal his phone and wallet.
Mr Keegan, a photographer who has been mooring his boat in Hackney Wick for about two years, said: “Everyone is feeling very anxious about it. There is a feeling of anxiety in the Hackney Wick area and the boating community.
“The neighbourhood has been really quiet. Everyone has sort of been on lockdown and trying not to go out after dark.
“Every single night there have been reports of a mugging posted on social media. It has brought the Hackney Wick community together trying to tackle this.”
A Met Police spokesman said: “Police were called shortly before midnight on Friday, December 23, to reports of a robbery involving two suspects on bikes in the Olympic Park area.
“A man reported having two phones and the contents of his wallet stolen. A knife was seen. Officers from Newham borough are investigating.”
