Spain arrests suspect over murder of US priest
Spanish police said on Wednesday they had arrested a man suspected of strangling an 80-year-old US Catholic priest during a robbery in the southern city of Málaga.
Father Richard Gross, who was from the US city of Boston, was found dead in January inside a holiday apartment he had rented in the centre of the city, where he was preparing to embark on a cruise.
Officers arrested a 40-year-old French national on Tuesday in the southern city of Seville, Spain's national police said in a statement. They said he was detained on suspicion of murder.
Another suspect was already in custody: a 27-year-old North African man arrested in late January. Police said they believed he acted as a lookout during the attack. Both men have criminal records related to theft.
Police suspect the two men followed Gross as he got out of a taxi the day he arrived in Málaga and followed him to the entrance of his holiday apartment, where the attack took place.
The two suspects then fled the scene with the priest's belongings, including his suitcase.
Underground economy accounts for a quarter of Spain's GDP
A recent report published by the London-based Centre for Economic Policy Research (CEPR) estimates that the underground economy in large countries represents 17 percent of GDP, while in developing countries this figure doubles to 33 percent of GDP.
Greece is at the top of the ranking in the EU, where the shadow economy represents 36 percent of the Hellenic nation's GDP, followed by Italy with 31 percent.
Spain is in third place with 24 percent. Furthermore, the study found that there's been a 7 percent increase in these illicit practices in Spain from 1999 to 2020.

Spain World Cup 2030 chief resigns after stadium fix allegation: reports
Spain's head of World Cup 2030 organisation resigned Wednesday after being accused of fixing the process to decide which stadiums would host matches to favour one city, reported Spanish media.
María Tato stood down from her post at the Spanish football federation (RFEF) following a report published by newspaper El Mundo which said ratings for potential venues were altered to favour Anoeta in San Sebastian, at the expense of Balaídos in Vigo.
"On 25 June 2024, Balaídos was among the 11 venues (in Spain), but on 27 June the list was modified," complained mayor of Vigo, Abel Caballero, on X this week.
"This is extremely serious, we demand that they explain to us who changed it, why and with what criteria."
The RFEF has been hit with various crises in recent years, including that of former president Luis Rubiales who resigned in disgrace in September 2023 after forcibly kissing Women's World Cup star Jenni Hermoso on the lips following Spain's triumph in Sydney.
