Coronation Street spoilers: is Carla Connor to blame for the factory collapse?

As the dust settles after the factory collapse and one family grieves the death of a love one, people grow desperate to find someone to blame.

A health and safety inspector arrives in Weatherfield and introduces himself as Wayne Hayes, who Roy and Hayley Cropper fostered many years ago.

Arriving at the station for questioning, Carla is shocked to find Wayne is the new health and safety officer. Feeling overwhelmed she decides to get away for a few days.

But Carla isn't the only one surprised by Wayne's reappearance. Though he's in town for sombre reasons, Roy is thrilled to reconnect with his old foster son.

Wayne agrees to help Roy research the origins of Sylvia's old ring. Later on, he and Brian come to the conclusion it may be from Egypt, brought back by servicemen stationed there.

Meanwhile back at the Bistro, Michelle tells Ali how proud she is of his quick thinking at factory, and Ali thinks it might be time for him to return to the medical profession.

When Robert arrives back in town he's evasive about where he's been for the past few days, and Michelle thinks something's up. She asks Ryan to keep a close eye on him.

But Michelle has bigger worries on her mind as she desperately tries to disperse gossip about Carla's involvement in the collapse, insisting that she couldn't have known about the state of the roof, as she would never had put peoples lives at risk.

When Rob realises Ryan has been spying on him on Michelle's orders he is furious, and fires Ryan on the spot. Rob tells Billy he's now got a vacancy and can take on one of his young offenders to work in the bistro immediately.

Despite Michelle's best efforts, people are still suspicious of Carla's involvement, with her absence only making her look more guilty.

But Sarah can't stop thinking about Gary's part in the tragedy, and tells him that unless he tells police about his involvement, they're through.

Meanwhile, Gary has finally been given some work by Jan and Anton. Seb overhears them celebrating at the pub, and is gutted to realise it's the same place he's been offered work, too.

Coming home from their celebrations, the good mood is shattered when Gary realises someone has broken into the yard and vandalised his van, doing off with his tools.

Sarah is convinced that Seb is behind the vandalism and tries to convince Gary to report him to police. But Gary is reluctant, and Seb riles him up by insinuating that the roof collapse was because of shoddy workmanship.

Meanwhile, Sinead and Bertie finally return home from the hospital, and are touched to find that Ken has decorated the flat with banners and balloons.

As Sinead fusses over the new baby, Ken reassures them they will make great parents.
