US network WB is to cancel cult TV series 'Angel'.

The show, which stars David Boreanaz as a vampire living in Los Angeles who tries to redeem his past evil deeds, will end after its fifth season.

'Angel' is a spin off  'Buffy the Vampire Slayer,' which also recently ended.

Creator Joss Whedon, who overhauled the show with new cast members after barely avoiding cancellation last season, said he was "heartbroken."

"It seemed like we hit our stride, so this is a big shock," Whedon said.

The show maintains a small but loyal cult-fan base, but WB executives decided the numbers were not high enough to justify the programmes cost.
