Monaco authorities detain then release a person in their probe of this week's explosion

MONACO (AP) — Monaco authorities said a person was arrested but later released Wednesday as they "very actively" pursue their probe of an explosion that reportedly wounded a Ukrainian tycoon with ties to Russia and two other people. A statement from the Mediterranean principality's prosecutor general said the person is a foreign national and was detained in Monaco in the morning. They were held in police custody "as further checks were deemed necessary" before being released in the afternoon, it said, giving no further information about the person or why they aroused suspicion. The explosion at an apartment building entrance in Monaco occurred late Monday. Monaco authorities haven't identified any of the injured but said they were a family and that they appeared to have been specifically targeted. Media reports identified Ukrainian construction tycoon Vadym Yermolaiev as being among the injured. He has said he renounced his Ukrainian citizenship nearly a decade ago, and he was targeted by Ukrainian sanctions in 2023 for ties to Russia. A woman and a child were also hurt. The prosecutor's statement described the blast as an attempted assassination and said authorities in neighboring France are assisting the investigation. It said the injured child has been interviewed in France but that the other two victims are still not in a condition to be questioned.
