A man has been arrested in connection with a bomb attack in Paris yesterday which killed an office worker at a law firm which was targetted in the attack.
An office secretary opened the wooden box package after it was delivered to the law office, and two explosives inside went off, killing her and seriously injuring a lawyer.
Judicial police entered the home of the suspect's mother, where he was living, the police officials said.
The man, said to be a 45-year-old architect, had allegedly harassed a lawyer in the firm two years ago, the officials said.
The building also housed another law firm co-founded by French President Nicolas Sarkozy and a Holocaust research foundation, though officials said they did not appear to be targeted.
After the arrest authorities were ruling out any possibility of terrorism, and continued a search for a delivery woman who dropped off the package, the officials said. Police investigators were questioning the suspect today.
