This is the moment paramedics and firefighters swooped on a street in Cardiff - but thankfully the dramatic scenes were all part and parcel of a new episode of Casualty.
The cameras began rolling in Adamsdown Square as crews filmed scenes for an upcoming episode of the long running BBC drama. Photos show a rapid response vehicle, an normal ambulance as well as a fire truck at the location - as curious residents looked on.
The BBC One drama's production team had already warned locals that the planned shoot would not involve a "real emergency" and was set to take place between 8am and 7pm on Monday, July 11.
Casualty follows the lives of A&E staff at Holby City, a fictional hospital in the south-west of England. In 2011, the TV production moved from Bristol to BBC Roath Lock Studious in Cardiff Bay.

Since then, the BBC drama has used locations such as a cul-de-sac in St Mellons and Lloyd George Avenue in Cardiff Bay to film some of its exterior shots.
Prior to Monday's filming, the TV series' production team notified residents of the area that filming would take place via a letter. The letter, which was put through letterboxes last month, reads: "We would like to inform you that an application has been made to the Cardiff Film Office to permit filming a couple of scenes for Casualty on Monday, July 11, on Adamsdown Square.
"We expect to be present between 8am and 7pm. The location manager added that most of the action will take place on the southern edge of the square and the area around the park will be closed for most of the day. "Traffic would be able to flow through the square on the far side of the park," he wrote.
