A DANGEROUS transgender sex offender has been jailed after she pretended to be a teenage boy to groom a 12-year-old girl.

Jacinta Brooks, 41, sent dozens of explicit messages to the girl, asking her to send indecent images of herself.

It was the third time Brooks had targeted children, after previously having sex with a girl under 16 and abusing another, Southampton crown court heard.

The mother of the latest victim said that not being able to protect her daughter from ‘this pathetic excuse of a person’ will ‘haunt me forever’.

Judge Nicholas Rowland branded Brooks a ‘danger to children’ after hearing the child suffered such severe trauma she was forced to leave school.

Brooks, who was known as Duncan Smart but now lives as a woman, was caught when police found messages as they investigated a different sexual allegation. The defendant, of Winchester, admitted three counts of inciting a child to engage in sexual activity and three of having indecent images and was jailed for 11 years.
