A shopkeeper and her 13-year-old daughter were left terrified when two masked men armed with a baseball bat and kitchen knife burst into their shop.
The incident took place at the Gilthill Store in Eastwood Road, Kimberley, shortly after 7.45pm on Sunday, April 11.
Lakmini Muthu was looking after the shop with her daughter while her husband Anthony Muthu, 46, slept in their house at the back of the shop.
The intruders, who wore a mask and had their hoods up, hit Mr Muthu over the head before stealing cash and cigarettes.
Police say the men then fled the scene and ran up Truman Street and onto Lawn Mill Road.
Mr Muthu told Nottinghamshire Live: "I was sleeping and so I didn't realise what was going on.
"My daughter and my wife were in the shop. They hit me in the back of the head and were asking 'where's the money'.
"He has then ran away from the house. I came back to the house and then we asked for help.
"I am worried about my daughter, she is scared and having trouble sleeping at night after what happened."
The two men targeted Anthony's wife Lakmini when they first arrived, brandishing a knife after bursting through the front door of the shop.
She said: "It was very scary.
"I was very shocked - I thought 'who is this?'
"They had a big knife, it all happened when I was in the shop - they also took some things. All I could see were their eyes, it was very scary."
Detectives investigating the incident are keen to speak with anyone who may have witnessed what happened, or seen two men acting suspiciously in the area at around the time of the incident.
DC Bethany Sumner, of Nottinghamshire Police, said: “Luckily nobody was seriously hurt during this incident but it was undoubtedly a shocking and deeply upsetting experience for the victims.
“Nottinghamshire Police takes robbery offences very seriously and will devote whatever resources re necessary into tracking down offenders and bringing them to justice.
"We’d particularly like to speak to anybody who may have seen two men on Truman Street or Lawn Mill Road shortly after this incident.”
