PARIS (Reuters) - France's anti-terrorism prosecutor said on Saturday an investigation had detected signs of "latent radicalisation" in an attacker who knifed four co-workers to death at police headquarters in Paris this week.

The assailant, an IT worker at the headquarters, went on a rampage on Thursday, killing three police officers and an administrative worker, and wounding at least one other, before being shot dead by police.
