The "Coronation Street" set has been targeted by thieves.
Scenes for the soap - in which Simon Gregson's character Steve McDonald unwittingly becomes a getaway driver when a shop is robbed - were being filmed in Bolton on Friday (22.03.19) when real thieves broke into a nearby "unit base" and stole electrical equipment.
A set source told The Sun newspaper: "The crew were very shaken up by the incident. Nobody is quite sure exactly what happened because it was all so fast, but it's a huge worry for everyone.
"They made off with a very expensive electrical generator, but it was obviously a targeted attack because of all the kit on site and it could have been a lot more."
"There has always been security on set and we often film on location around Manchester and the surrounding area, but going forwards we're talking about increasing that to ensure there are no repeats of this."
A police spokeswoman said: "Greater Manchester Police were yesterday called to reports of a suspected armed robbery at around 11.30am."
ITV confirmed the robbery, telling the Mirror: "We can confirm a small domestic generator was stolen during a low-level opportunistic theft from the unit base of filming today for Coronation Street whilst the crew were on location in Bolton."
The episode which was being filmed when the incident took place will air on ITV on May 17.
