Two brave shopkeepers fended off an armed intruder during an attempted robbery at their mobile phone shop.
Security camera footage shows a masked man brandishing a stun gun while threatening the staff to open the cashier.
But the pair remained calm and worked as a team to fight off the intruder.
The 29-year-old manager grabbed the robber's handgun and pointed it towards the robber in defence before he pulled out a grenade.
While she was distracting the intruder with the weapon, her shop assistant emptied a fire extinguisher on the robber and threw a chair at him amid scenes of chaos.
The robber, who wore a hooded jacket and covered his face with a surgical face mask, fled the scene empty-handed.
According to Megapolis , the shop staff had triggered a hidden alarm which alerted to police to the shop.
Russian national guards arrived and arrested a 40-year-old suspect, whose name has not been disclosed.
Officers found an array of weapons including cartridges, a baseball bat and fake grenades in the suspect's car.
A decision is yet to be made on charges.
