A thug who threatened to throw acid at a woman and 'blow her up' during his campaign of terror has been jailed.

Nathan Brown, 35, from Caerphilly in Wales, hurled vile abuse at his victim and assaulted her by grabbing and squeezing her breast.

Prosecutor Bethan Evans said: 'She screamed out in pain as he did so after pinning her up against her front door – she was left with bruising.'

He told the woman, who has now been left with PTSD, that he had access to 'caustic chemicals' where he worked and said he could 'throw it' in her face.

'This was a threat to use acid,' Miss Evans told Merthyr Tydfil Crown Court during his sentencing.
