She has been traced to Germany, reports French BFMTV, citing a source close to the ongoing investigation. It is not clear whether she has been arrested.
A Ukrainian oligarch, a woman and a teenage boy were injured when an explosive device detonated at the gate of a residential building in Monaco on Monday evening.
Photos taken in connection with the incident show a person running around wearing a black jacket and fisherman's hat. Monegasque police believe the person was trying to look like a man.
