Michael Boulding and his brother Rory tonight signed for City.
Both strikers penned two-year deals at the club’s Scottish training base in St Andrew’s.
They had travelled up by train to meet their new team-mates this afternoon in Edinburgh, where the squad were enjoying a “bonding” session at an indoor assault course.
Delighted City boss Stuart McCall said: “Michael was our first choice as a striker because he offers something different to what we’ve already got.
“He’s someone who can get in behind the defence with a bit of pace.
“I’m also pleased to have Rory on board. He’s on exactly the same contract as Luke Medley was on and will be there to push the main strikers.
“With the other lads we’ve already got, hopefully we are now going to have enough firepower to be up there challenging.”
