A HUGE 3.5 tonne cocaine haul discovered on the Costa del Sol could easily exceed €120 million in value, Spanish cops have said. 

The mammoth haul was found hidden in salt in a home and a warehouse in Estepona.

The stash is believed to be linked to the network of huge alleged drug boss Sito Miñanco, who was arrested in Algeciras last week.

The find is the biggest ever in Malaga and one of the biggest ever on Spanish soil.

Five people have been arrested but this could increase as investigations continue.

Officers estimate the cocaine found has a street value of just over €120 million.

Just over two tonnes were found in a house next to the luxury H10 Estepona Palace hotel in Estepona.

The rest was in an industrial warehouse nearby.

The cocaine was in hidden packages inside bags containing salt.
