National Police officers have arrested members of a gang that stole two kilometres of acoustic barriers that ran along a stretch of dual carriageway between Malaga and Torremolinos.
All seven members of the gang are Spaniards aged between 21 and 34.
The barriers, installed to reduce noise pollution, were valued at more than 80,000 euros. After being removed by thieves they were cut into pieces and then sold as scrap.
During the investigation, police found 350 kilos of iron and 16 kilos of aluminium which had come from the barriers at a scrapyard on the Guadalhorce industrial estate.
The 28-year-old in charge of the scrapyard was arrested on suspicion of receiving stolen goods.
The gang is also believed to have stolen 19 telephone cables worth around 155,000 euros, which were then also sold to scrapyards in the city.
