Workers at a controversial drug testing laboratory have won a High Court injunction protecting them from harassment by animal rights protesters.
The firm has research centres in Suffolk and Cambridgeshrie
A judge granted the interim order to employees of Huntingdon Life Sciences (HLS), which conducts experiments on animals at its research centres in Cambridgeshire and Suffolk.
The order bans protesters from approaching employees' homes and places exclusion zones at the two centres.
It comes into force in time for a large anti-vivisection demonstration expected in Cambridge on Saturday.
The new order was granted to HLS managing director Brian Cass on behalf of more than 1,000 employees.
Mr Justice Pitchers said some protesters targeted individuals rather than the company as a whole.
He described such tactics, including publishing employees' home addresses, as "very much like stalking".
He said: "I have been told that an order of this kind will be helpful in keeping the rally on Saturday within lawful bounds."
The injunction states protesters will be restrained from pursuing a course of conduct which amounts to harassment of the employees and their families.
A full hearing to determine whether the injunction should remain in place is expected to be held on 14 May at the High Court.
Representations will be made on behalf of various animal rights groups.
