After escaping prison with the help of former cellmate Robbie Sloan, the Corrie bad boy, played by Gray O'Brien, undertakes an armed siege at knicker factory Underworld.
According to the Sun, two body bags are carried out at the end of the siege, but the identity of the victims has not been revealed.
Armed with a gun, knife and petrol can, Tony plans to kill cheating ex-wife Carla Connor (Alison King) as well as Hayley Cropper (Julie Hesmondhalgh) as revenge on her husband Roy (David Neilson), who helped convict him.
But Maria Connor (Samia Smith), Roy and Becky McDonald (Katherine Kelly) get drawn into the scheme.
A source told the Sun: "By the end of it there are armed police and the street is evacuated and sealed off.
"When it is all over, two body bags are carried out."
Tony was sent to prison for murdering Carla's lover Liam Connor (Rob-James Collier) and trying to kill Roy.
