The windows of Sunspot Hair, Tanning and Beauty Salon on Station Road, Epworth, were shattered early yesterday (Sunday) evening.
Stunned owner Leesa Sharpe said: “It’s quite shocking. Can’t understand who would deliberately go out on an early Sunday evening and smash all my windows and door panes.
“All 12 panes of glass have been smashed with some sort of large metal object at about 6.40pm it seems.
“It had to be more than one person and they must have known the Onestop store next door was open and they could have been seen.
“I find it unbelievable.”
The salon is closed until Wednesday.
Police are investigating the crime. The side of the salon was also damaged when thieves tried to ram raid an adjacent service till recently.
