LONDON – British Muslim lawmaker Rupa Huq received a suspect package Tuesday, March 13, containing anti-Muslim letters and a sticky liquid, making her the fourth Labour MP to receive such hateful messages over the past 24 hours.

“The affected areas were temporarily cordoned off but no evacuation was necessary,” a Parliamentary spokesman, BBC reported.

Westminster offices were sealed off and three people were taken to hospital as a precaution.

The spokesperson added later that items of mail containing suspicious substances had been investigated by the Met Police and were not found to be hazardous.

Receiving the letter, Rupa Huq, MP for Ealing Central and Acton, said her package was a “Punish a Muslim” letter.

Parliament has emailed all staff, warning them to “be on the alert for suspicious items of mail”.

Earlier this week, hate letters were sent to random UK homes asking the recipients to join a national day of violence against Muslims in April.

The letter asked people to carry out violent acts including verbal abuse, removing a woman’s hijab or head-scarf, physical assault and using acid as a weapon.

“Staffer who went to the hospital now discharged. There is a definite pattern. It was the letter that did the rounds at weekend and subject of the Parliamentary urgent question yesterday which was received. Normal service now resumed – though scary experience,” Huq tweeted.

She later told the BBC it was worrying the packages had got through security in the House of Commons but “it was even more worrying that someone out there thinks it is open season on Muslim MPs”.

Labour leader Jeremy Corbyn said the letters and packages being circulated were “utterly contemptible”.

“Labour is committed to tackling Islamophobia and anti-Muslim hate crime, as well as all other forms of bigotry, racism, and xenophobia,” he said.
