In the video, seen by ECHO, two passengers can be heard in a heated argument over a woman not wearing a face mask.
Witnesses said a number of passengers began to criticize a young passenger for not wearing a mask, prompting others to jump in to defend the woman’s daughter.
At one point, the driver can be heard telling a woman wearing a mask under her nose to “don’t lecture people about masks when you can’t wear one properly”.
A witness told ECHO: “The argument took place on a number ten bus going into town and it started when a young girl got on the bus without a mask.
“A man and an older woman started ganging up on her and a huge argument broke out.
“The bus driver had to get up from his seat and came to ask what was going on and he told a woman that she was not even wearing her mask properly.
“This woman then stormed off the bus and said she was going to report the incident. ”
Face masks have been mandatory on public transport in England since June 15, requiring all passengers to wear some form of face mask on buses and trains.
Those who do not wear a face mask on public transport could be fined or denied entry on public transport if deemed necessary.
Arriva said the wearing of face masks remains “mandatory for clients” although it allows some exemptions.
A spokesperson for Arriva said: “The safety of our customers and employees remains our priority. Wearing masks remains compulsory for customers when using public transport (exemptions apply).
“We have clear guidance and signage for customers regarding this and all other social distancing measures in place on the bus, via social media and our website for more information please visit arrivabus.co .uk. “
