Paul Wotton has continued to add to his Torquay United squad, with two players who he is familiar
Comfortable in a number of positions, Threlkeld, 30, arrives at Plainmoor on a one-year contract and brings with him a wealth of EFL experience.
After rising through the ranks at Bolton Wanderers, Threlkeld first signed for Plymouth Argyle as Derek Adams attempted to rebuild a side who had lost the 2016 League Two play-off final to AFC Wimbledon.
He then went on to establish himself as a firm fan's favourite at Plymouth Argyle, before moving on to Salford, Bradford and Oldham. He also had a brief spell in Belgium with Waasland-Beveren before returning to Home Park in the second half of the 2018-19 season on loan.
After departing League Two side Morecambe at the end of last season, Threlkeld now returns to Devon to link up with Gulls boss Paul Wotton, who was first-team coach at Argyle during the player's first spell at Home Park and assistant manager during his second spell.
Threlkeld was then swiftly followed by the arrival of goalkeeper James Hamon who, of course, played under Wotton at Truro City. Former Exeter City keeper Hamon also had a brief loan spell at Plainmoor during the 2020-21 season.
Wotton then added young striker Jaydn Crosbie who netted 37 goals in 48 appearances for Mangotsfield Town in the Hellenic Premier League and centre back Sam Dreyer, the son of former Luton defender John Dreyer who had a loan spell with Torquay during the 1985-86 season.
