But Ny says she didn't cause trouble and is treated differently due to looks

Says it asked the group to leave its branch in Hull after 'causing problems'

Ny Richardson says manager asked to see ID to prove she was a female

A teenage girl claims she was asked to leave a McDonald's restaurant for using the women's toilets - because staff mistook her for being a boy.

McDonald's says that Ny Richardson, 16, was part of a disruptive group at the St Andrew's Quay branch, in Hull, East Yorkshire, and was asked to leave after causing problems in the restaurant.

But Ny, who is a lesbian, claims she did not cause trouble and said it was not the first time she has been treated differently because of her appearance.

Police, who were called to the restaurant on Tuesday night, say a group of youths became abusive after a customer complained about someone they wrongly believed to be a boy in the women's toilets.

Ny said: 'I ordered my food and left it with my girlfriend as I went to the toilet. When I was in there, someone told me to get out and when I sat back down, the manager came over and told me that I needed to leave because I have been in the girls' toilet.

'I said to him, 'Why do I need to leave? I'm a girl, can you not tell by my voice?'

'He then asked me to show some ID, but when I didn't have any he told me to get out and he rang the police.

'I'm used to being accused of being a boy, but this time I was humiliated in front of the whole restaurant. I think his attitude was disgusting and I'm still angry about it now.'

Police have confirmed they were called to the McDonald's after a group of youths Ny was with became involved in an 'altercation' with staff.

Ny, who is a student at Kingswood Academy, said she came out as gay when she was 12 years old. Despite the full support of her parents and friends, she said it has led to her being abused.

Ny said, on one previous occasion, some women hit her with their handbags when they saw her in toilets. She now resorts to using the disabled toilets whenever she can, but it was occupied on Tuesday.

Ny's mother, Leigh Richardson, stood by her daughter.

'She is who she is and people need to accept that,' Mrs Richardson, of Beverley Road, said. 'She shouldn't have to justify herself to anybody.'

A McDonald's spokesman said: 'We can confirm a group of individuals were asked to leave our St Andrew's Quay restaurant, following several complaints about inappropriate behaviour.

'This group has been asked to leave the restaurant on numerous occasions over the past few days, culminating in the police being called on Tuesday evening. These actions have been taken due to unacceptable behaviour only.'

A Humberside Police spokeswoman said: 'Officers were called to the St Andrew's Quay branch of McDonald's following reports a group of youths being abusive.

'An altercation had ensued between the youths and staff after a customer complained a person they wrongly believed to be male was in the women's toilets.
