“DESPERATE” robbers targeted a charity shop escaping with cash and assaulting staff.
Two men entered the Emmaus Home charity shop in Colchester High Street at 3.30pm on Friday, January 24.
While one distracted a member of staff the other opened the till and stole £180.
But as the thieves were trying to make their getaway the employee tried to stop them - she was hit and pushed to the floor.
Acting Detective Sergeant Pete Coley, of Colchester CID said: "These were clearly two desperate thieves who have targeted a charity.

“Thankfully her injuries are minor.
"We are determined to find these men and get them arrested.
“We urgently need to hear from witnesses who were in the area of Colchester High Street that day who might have seen the thieves running from the scene.”
