Bury have added free agents Adam Lockwood, Marcus Marshall and Lateef Elford-Alliyu to their squad.
Defender Lockwood, 30, spent six years with Doncaster but
left the Keepmoat Stadium
following their relegation at the end of last season.
Former Rotherham United winger Marshall,
22, ended the season on loan at Macclesfield and has signed a one-year deal with the Shakers.
Elford-Alliyu moves permanently to Gigg Lane after a
loan spell last season.
The 20-year-old striker scored twice in 13 games for Richie Barker's side, who finished 14th in League One in 2011-12, and was
recently released by West Bromwich Albion.
The trio join ex-Sunderland goalkeeper Trevor Carson, who
confirmed his move to Bury
