In the first episode of a four-part series, Famous and Fighting Crime stunned viewers as a criminal suspect threatened to stab Loose Women's Penny Lancaster with a dirty needle.
The new Channel 4 programme sees Penny, presenter and model Katie Piper, Made in Chelsea's Jamie Laing, Gogglebox's Sandi Bogle and comedian Marcus Brigstocke volunteer as special constables with the Cambridgeshire police force.
And in the premiere, Penny was forced to confront demons from her past as she approached a threatening member of the public.
The Loose Women panellist found herself chasing down a suspected shoplifter who shockingly threatened to stab Penny with a "dirty needle".
Viewers were stunned as the events unfolded, with many praising Penny for her bravery.
One viewer tweeted: "Penny chasing that girl was brave! What our police men and women do and go through to keep our streets safe is unreal!"
While another wrote: "Honestly Penny shouldn’t have been left on her own to chase the girl imagine if she got stabbed."
Earlier in the episode, during her gruelling first day of training, Penny broke down after a constable simulated a possible scenario pretending to be a violent suspect. The training left her shaken as it brought back memories of a time she was threatened by a man.
Jamie Laing was also rather chuffed with himself after he singlehandedly chased down and caught a suspect, helping the constables to arrest the individual.
Famous and Fighting Crime airs Mondays at 9pm on Channel 4.
