A letting agent from South London is threatening to sue easyJet after a flight she and her family were on was forced to make an emergency landing in Portugal following a brawl over The Karate Kid kicked off in mid-air.

The flight from Lanzarote to London Gatwick descended into chaos last year when a woman confronted a five-year-old boy for watching the 2010 remake of classic film on his iPad.

The mother of the five-year-old, 26, claims that her son was watching with “the volume set low”, reported The Sun.

She also alleges that the woman’s other half grabbed her disabled partner by the neck.

Speaking to The Sun, the letting agent, said: “This incident involved racial abuse, discrimination, and physical assault. My son was left extremely scared and distressed.”

She said her family should have been supported and that she had not heard back from easyJet despite nine months of complaining to the airline, which has banned those involved from future flights.

A spokesperson for easyJet told the press: “Safety is our highest priority. We do not tolerate disruptive behaviour.”
