Grimsby Town have completed the signing of midfielder Peter Till on a permanent basis after a successful loan spell. Till, 26, joined the League Two outfit in November and has sufficiently impressed in his seven appearances to earn a contract at Blundell Park.
The right-winger has signed a two-and-a-half year deal with Grimsby after Birmingham released him.
Till only made one appearance for Birmingham and had loan spells with Scunthorpe, Boston and Leyton Orient.
