Alyson Hannigan granted restraining order

Actress Alyson Hannigan has been granted a restraining order against a man who allegedly threatened her online.

The How I Met Your Mother star requested a protection order against John Hobbs, who she claims has been harassing her via a number of social networking sites.

In the request, filed by her lawyers in Los Angeles, Hannigan claims that Hobbs is "mentally unstable and was recently discharged from a mental hospital".

The restraining order also protects her actor husband Alexis Denisof and their daughters, Satyana and Keeva Jane.

A hearing has been set for 6 March to decided whether the order will be made permanent.
