Leicestershire have released the 23-year-old seamer Nick Walker from his two-year contract.

Walker, who joined the county in 2006 after a successful trial, has decided to follow a career in the City. He took 32 wickets in his 13 first-class appearances for Leicestershire, following his move from Derbyshire, and took a best of 5 for 59 against Somerset.

Walker's decision may in part have been prompted by the recent recruitment of Garnett Kruger and Nadeem Malik to bolster the fast-bowling attack.
