Sussex have confirmed that Steffan Piolet has signed a one-year contract with the county for next season.
The 25-year-old spent the latter part of last summer on loan at Hove from Warwickshire, although he made only two appearances for the Sussex second XI.
Piolet, who began his career with Sussex before joining Warwickshire in 2008, is regarded as a one-day specialist but he is determined to make an impact in all formats of the game in 2014.
"I'm delighted to be back home with Sussex," said Piolet, who has made 51 appearances in Twenty20 cricket but only four in the County Championship.
"I always wanted to play here at some point in my career and I'm looking forward to fighting for a place in all forms of the game."
Sussex professional cricket manager Mark Robinson said: "We're really excited at the prospect of having Steff on board. Being a local lad, having played Youth and Second Team cricket with us, he is somebody we know really well.
"Steff has a hunger to play in the longer form of the game and the makeup of our squad means he has every chance of getting some opportunities to prove he is more than just a very good one-day player.
"We appreciate and admire Warwickshire's willingness to do what is best for the player by releasing him and allowing us to pick up the last year of his contract."
