A woman who was gang-raped in Pakistan has accused a police officer of raping her in a further attack when she went to report the crime.

The woman, from the city of Uch Sharif in Pakistan, claims the officer took her to a house on the pretext of wanting to interview her, and then attacked her.

She also alleges that the police officer filmed the attack and threatened her if she reported it to anyone.

The assistant sub-inspector has now been arrested, according to English-language newspaper Dawn.

A woman in Pakistan claims a police officer raped her after she had gone to a police station in Ahmedpur East (pictured) to report an earlier gang-rape attack

The woman had gone to the police station in Ahmedpur East to register the earlier case, in which she was allegedly raped by two men.

She said the police officer had summoned her on February 12 and claimed he wanted to record her witness statement.

Pakistan's police have been under fresh scrutiny this year amid a wave of deadly shootings of suspects.

In January more than a dozen counter-terror officers were arrested after a middle-aged couple, their 13-year-old daughter and another man were shot and killed.

Police initially claimed the incident was a shootout with insurgents but family members and witnesses said police had killed the four in cold blood.

The shooting sparked widespread outrage, with hundreds of mourners gathering in Lahore and chanting anti-police slogans.

Pakistani PM Imran Khan said he was 'shocked at seeing the traumatized children who saw their parents shot before their eyes.

Thousands of people have died in so-called 'encounter killings' in which police shoot suspects who are allegedly resisting arrest.
