What region is 01132 for phone numbers?

Just got a weird phone call on my mobile. She (yes it was a girl oO) didn't withdraw. I answered and she said first 'who is this' I am like 'who are you?'

Then it's all a bunch of fast speech I didn't quite catch. I didn't answer, so she went 'hello? hello?' and hung up after a while. None of my friends recognize the number.

01132 xxxxxx - what region is that for the UK, does anyone know? I tried looking it up but no avail. (I'm in Leicestershire).

Strange... I've never been to that area before.

I just remembered my sister is at Leeds University, so I've just sent her a text asking what the sammy hill is going on. It's not her number and sounded nothing like her.
