A retired superintendent has accused a police force of “shadowy behaviour” after discovering it had recorded a “non-crime hate incident” against her without her knowledge.

Catherine Larkman said Lincolnshire police had made a record of the “hate incident” in September last year.

She was accused of “targeted harassment”, which had been “aggravated by hatred of transgender people” through tweets that she had posted.

However, the former officer said she found out about the police record in March only after formally requesting information about any investigations into her conduct.
