Police in Slovakia have released all seven people detained in connection with the murder of investigative journalist Jan Kuciak and his girlfriend. “During the legal timeframe – 48 hours – (police) checked and searched for facts needed for an indictment. After the 48 hours passed, the persons were released from detention,” police spokeswoman Denisa Baloghova said in a statement, as quoted by Reuters. The two were found shot dead in their home last weekend, representing the first murder of a journalist in the country. Kuciak had been looking into suspected mafia links among Italian businessmen in eastern Slovakia at the time of his death.
