Wild footage shows a massive brawl breaking out over a pool chair at a Spanish tourist resort — leaving a 13-year-old girl covered in blood with a broken nose.

Tourists were seen pulling hair and wrestling at the Santa Susanna hotel in Catalonia, about 40 miles from Barcelona, according to the Sun. 

It started when the “innocent” 13-year-old British girl sat in a chaise lounge and “had no idea that it had already been in use by another family,” one witness told the paper.

One topless man unleashed a flurry of blows on the 13-year-old bikini-clad British girl, as another yob pulled her hair as others around them joined in to what looked like “a full-scale riot,” the witness said.

“He didn’t utter a word, just piled in. It was unbelievable; totally sickening. How could a grown man act like that to anyone, let alone a child?

“The girl was led away with blood streaming from her nose. Women were screaming for their kids to get out the pool,” the witness added, likening the brawl to “a saloon-bar brawl.” 

The teen was left bloodied with a suspected broken nose, while others were left with cuts and black eyes amid the wild scenes.

Staff helped break up the fight and called police, although it does not appear any arrests were made, the Sun said.
