Swindon chairman Lee Power has confirmed the League One leaders have signed Redditch striker Jermaine Hylton on a free transfer.
The 21-year-old was not under contract at the Southern League club and joins Town following the expiration of a seven-day notice of approach.
Hylton, who has scored 45 goals in two seasons, has agreed a two-and-a-half year deal at the County Ground.
"There were a number of clubs that were interested," Power told BBC Wiltshire.
"Birmingham and a number of other teams offered him a deal so we're pleased to get him."
The move has been the subject of controversy, with Redditch chairman Chris Swan lodging a complaint to the Football Association suggesting Swindon's approach for Hylton was illegal.
Power insists the club do not have a case to answer, as Hylton was not under contract at Redditch.
"It's difficult in non-league. Redditch decided not to have him on a contract so we put in a seven-day approach," said the Swindon chairman.
"We offered them a pre-season game and for whatever reason they decided not to go for that.
"The lad has signed and now he's officially a Swindon Town player."
