He was identified by the last names of Rivera Solano. He and two companions were detained.
Fuerza Pública officers, acting on telephoned information, detained the trio at a cell tower in Atenas. The three had entered the site after cutting the locks, said the Poder Judicial.
Prosecutors are seeking three months of pre-trial detention. In all, officials said that four towers had been the location of thefts.
The object was the lead batteries in the base of the towers. The Poder Judicial said that the batteries are a backup system in case the electrical current fails. The cell towers would continue to handle calls. The value of the stolen batteries was estimated Monday at $30,000.
Had the power failed early Saturday,the communities of Palmares, Atenas, Grecia, Orotina and La Garita de Alajuela would have been without Movistar cell service, said the Poder Judicial.
