The arrests were carried out over three consecutive days following an investigation that has clarified 107 criminal acts: 90 counts of damage and 17 of public disorder, as reported by the National Police.

The investigation began last December, when officers detected several acts of vandalism committed following the same pattern. Among the techniques used was the so-called 'palancazo,' a common method among some graffiti artists that involves activating the emergency brake to stop the train and using the stop to spray paint the carriages.

According to the Police, the detainees sought to gain recognition within the graffiti scene through high-impact and risky actions, a practice known as 'getting up'.

In one of the investigated incidents, officers confirmed that the individuals used spray cans like blowtorches and displayed aggressive behavior towards passengers. Furthermore, they resisted both security guards and the intervening police officers.

During the operation, tools such as angle grinders, master keys for accessing railway depots, and numerous spray paint cans were seized.

The arrested individuals have been charged with offenses of damage and public disorder. All have been brought before the judicial authorities, and in the case of minors, before the Juvenile Prosecutor's Office.
