A new police officer accused of urinating in a Yorkshire clothes shop fitting room while drunk off-duty told a disciplinary hearing she was “mortified” to be questioned about it in a busy shopping street.

Probationer Pc Amelia Shearer is facing the sack from Cleveland Police for gross misconduct following the alleged incident in the York branch of Urban Outfitters last September.

The retailer paid £492 to have the cubicle professionally cleaned and the store’s nine fitting rooms had to be closed afterwards, a disciplinary hearing at Middlesbrough’s Riverside Stadium has heard.

Pc Shearer denies the allegations that she urinated in the store and that she lied to her boss afterwards.

The disciplinary panel was told she had gone to the city with a friend and they had a “bottomless brunch” at Vodka Revolution, sharing a bottle of prosecco and consuming three cocktails in 90 minutes, as well as eating a breakfast pizza.

They went to another bar where they had nachos and she drank a Jack Daniels and coke before going to Urban Outfitters.

Pc Shearer was alleged to have asked if the store had toilets before going into a cubicle and urinating.

The officer, who studied a Masters in criminal investigations before achieving her childhood dream of joining the force, denied that, telling the hearing she would not expect such a shop to have public conveniences.

The Middlesbrough-based Pc told the panel she was drunk in the shop, and described her and friend as “loud and giggly”.

She denied urinating, and said: “I haven’t done that, I went to the changing room to resolve an issue with my underwear.”

Less than an hour after being asked to leave the store, she said she was questioned in a nearby street by a North Yorkshire police officer.

Pc Shearer told the hearing: “I was mortified that the allegation had been made and it was trying to be resolved in a busy street where there was people walking past.”

She said she repeatedly mentioned that her job was at risk, explaining: “It is drilled into us from the beginning, if you are a probationer they can get rid of you really easily.”

The next day, a Sunday, she spoke to Inspector Christian Duree on the phone and explained to the panel that she gave him an “abridged version” of events, not mentioning that she went into the cubicle to deal with the underwire in her bra.

The force claims that she lied to him about what happened that day.

Olivia Checa-Dover, for the force, told the panel the evidence against the officer was “overwhelmingly strong”, and the two members of staff who gave evidence were telling the truth.

Joan Smith, for the defendant, said she had consistently denied urinating.

Ms Smith told the panel: “The only person that can give you credible, sincere evidence on what was going on in that changing room is Pc Shearer.”

Earlier, the officer wept as Inspector Duree praised her performance as a probationer.

He told the hearing: “From my experience as a police officer she has been absolutely spot-on, an excellent officer.

“She deals with members of the public exceptionally well.

“Her performance as a probationer was excellent.”

The hearing was adjourned until Wednesday when the panel will give its decision.
