LONDON, Dec. 23 (UPI) -- Police in London arrested a 29-year-old Turk and recovered a large kitchen knife believed used in a stabbing spree earlier Thursday.
One man died and five others were wounded in the carnage.
Chief Superintendent Simon O'Brien said the person they had detained had a history of mental illness, Sky News reported.
"It's very difficult to know what prompted this," O'Brien said.
Police had been looking for a man with a knife who had driven between various locations, attacking his victims randomly in an hour-long frenzy this morning.
Police have said the dead man was aged 58 and married with a child.
The wounded included four men and one woman who were taken to a North London hospital.
"It seems the suspect was getting out of his vehicle, picking people at random, stabbing them and then getting back in his vehicle," said O'Brien.
