This system, known in prison slang as “fallas” or “brief notes,” involves rolling a paper with text around a battery, which acts as a weight to throw it from one module to another. The messages, according to investigations, detail alleged illicit dealings, including exchanges of substances and requests made through third parties.

The most recent case occurred this week when an inmate was caught throwing these objects from module 9 to 11. When asked to undergo a routine search, the inmate became violent, throwing more batteries and lunging at the officials, who managed to control the situation.

Prison sources have indicated that this is not the only practice for inter-cell communication, also mentioning the use of shoes thrown between modules for the same purpose. Prison workers emphasize that these clandestine methods are part of common inmate dynamics to circumvent regulatory controls.

This incident marks the fifth serious one recorded at the Alhaurín de la Torre prison in just two months, according to the Tu Abandono Me Puede Matar (TAMPM) Union. The organization believes this figure reflects a growing deterioration of security within the center and holds the General Secretariat of Penitentiary Institutions responsible for not adopting sufficient measures.

The union demands an urgent reinforcement of staff, more material resources, and a review of penitentiary classification criteria. They also denounce a “lenient approach” in management, citing a March 12 case where an inmate, previously classified in the first degree for assaults, attacked two professionals after disobeying rules during Ramadan. The prison management's proposal to classify him under a closed regime was rejected by the General Secretariat of Penitentiary Institutions.
