THIS is the moment a migrant boat arrives on a Spanish holiday beach before those on board are chased and tackled by angry locals.

Around a dozen of those who arrived on the boat were detained, with some held by beachgoers until authorities arrived.

The shocking incident unfolded on Sotillo Beach in Castell de Ferro, Granada in the afternoon on Sunday.

Footage shared on social media shows a speed boat with young men on board arriving at  the shore at around 2pm.

Those on the boat are captured diving into the water in front of stunned holidaymakers and locals.

They then swim to the beach before attempting making a run for it.

But locals are seen tackling some of the migrants to the ground, whilst others manage to escape.

A clip shows a beachgoer in swimming trunks pinning one man down whilst he appears to beg to be let go.

Later footage shows authorities taking those who arrived on the boat to be detained.

Witnesses branded the scenes as “surreal”.

Restaurant owner Alberto Garcia told local newspaper Ideal: “We all stood there staring, not quite knowing what was happening.

“At first, we assumed it was just a leisure boat, but once we noticed them tossing items into the sea and individuals beginning to disembark, we understood something was amiss.”

“What surprised us most was that the boat was moving very slowly, as if they weren’t in a hurry or afraid.

“They went in where there were most people, as if nothing had happened, and stopped five metres from the shore.

“Then they jumped off one by one, and the four remaining on board, some of them hooded, calmly turned around and left.”

Around 13 men, believed to be of Moroccan origin, are believed to have jumped out of the boat.

According to witnesses, some of the migrants ran along the beach as soon as they reached dry land, while others tried to blend in with the crowd.

However, some beach goers detained them until the Guardia Civil arrived.

The Polica Local de Castell de Ferro added: “The lifeguards alerted us, and we managed to catch one on the street. Then we helped identify two more.

“The Civil Guard did the bulk of the work and managed to arrest nine.”
