By MyFM's Rick Michaels - Holliston Police are hoping another piece of information about the armed robbery of the TD Bank on Washington Street last month will result in more tips to help find the suspects. Holliston Police now say one of the two masked robbers dropped an umbrella on the way into the TD Bank with the other picking it up on the way out. On the day of the robbery, October 24th, it was not raining. Police are hoping someone may remember seeing a person with an umbrella on that day. If you think you may have seen something, no detail is too small, call Holliston Police.
