A third person struck the victim's right leg with an unknown object from behind, causing the victim to fall to the ground in severe pain.
The victim was then struck on the head with the same unknown object by the third person.
While laying helplessly on the ground, the victim had his wallet and bag taken from him by the trio who then fled across the bridge, heading towards Main St.
Crawford branded it a cowardly attack on an innocent passer by and police were committed to holding those responsible to account.
All three wanted men were thought to be 1.82m tall and wearing dark clothing, with hoodies pulled over their heads.
