Bassetlaw MP John Mann has spoken of his shock over the killing of a solider in south-east London yesterday.
The attack happened in Woolwich in broad daylight at 2.20pm as horrified witnesses, including children, looked on.
Eyewitnesses say the victim, wearing a Help For Heroes t-shirt, was hacked to death by two men shouting Allahu Akbar - God is Great.
The two men were later were shot and wounded by police and spent the night under arrest in hospital as counter-terrorism police investigate the killing.
Mr Mann said of the incident: “It is crazy that there are people full of hatred and madness in this country as well as elsewhere in the world.”
“We need to be vigilant against them.”
“It’s concerning that the intelligence service had these people on their radar.”
“We need to get to find out exactly what has gone on there. We have to be arresting these terrorists.”
Police swooped on a house in Hotchkin Avenue in Saxilby this morning in connection with one of the men.
It is thought that Muslim convert Michael Adebolajo - one of the suspects in the attack - was registered as living at the address in 2003.
