Police advise Londoners to stay vigilant after a knife attack left one person dead and five others wounded. Julie Noce reports.
Londoners were on edge Thursday morning after a stabbing attack in Russell Square the night before. Police say a 19-year-old man has been arrested for fatally stabbing one person and wounding five others. A cordon has been set up around the scene, which is close to the site of the 2005 suicide bombing. Some people are trying to remain calm while others say they're nervous. (SOUNDBITE) (English) LONDONER, CAL STRODE, SAYING: "I think that the recent attacks in the rest of Europe have got everyone on high alert and I think that there is a lot more anxiety running through London right now." (SOUNDBITE) (English) LONDONER, ROBERT BURNS, SAYING: "I look at the statistics - there are about two million people in central London at any one time. If one person is killed, the chances are it won't be me. It's the only way I can look at it and still feel comfortable." Police said mental health was a 'significant factor' in the attack. The other injured people - one woman and four men - were treated in hospital and three were later discharged.
