An investigation has been launched after teachers on a school trip allegedly ended up in a drunken brawl that frightened pupils.
Teachers and pupils from Stanley Park High School in Carshalton went on a sports tour to Barcelona over half term at the end of May.
But the visit was marred by teachers drunkenly fighting each other, it is now alleged.
The school said the claims are being taken "extremely seriously" and have warned action will be taken if the allegations are proven.
One parent, who asked not to be named, said: "[My child] sent me a text message saying how scared she was to go to sleep because there were drunk teachers fighting.
"She said they were all teachers and were calling each other very rude words.
"They hit each other and the students were all very scared.
"One [teacher] came away with a black eye.
"There was another girl who wasn't very well on the trip and they couldn't find the teacher who had their medication because they had gone drinking!"
The parent has called on the school to sack the teachers they have alleged were involved.
The school is investigating the incident and issued the following statement: "We are aware of an allegation relating to a recent school visit to Spain.
"We are taking the complaint extremely seriously and are currently conducting an internal investigation; appropriate action will be taken if necessary."
