A union is threatening to withdraw 143 members of staff from Morton Hall Immigration Removal Centre in Lincolnshire, claiming they're being subjected to abuse on a daily basis.
The Prison Officers Association say staff are constantly spat at, kicked, verbally assaulted and punched whilst at work at the centre in Swinderby. The union also claims staff were recently forced to draw their batons during a fight between groups of detainees.
The POA wants the UK Border Agency to sign up to a 'zero tolerance approach on violence. The Border Agency itself though says the centre is already a safe place for staff and detainees.
