Broken glass Tigwells Field

Please don't send anyone out, I have already swept up the glass. This has happened at least 3 times now on Recycling collection day. Several piles of small glass fragments in 3 or 4 places in Tigwells Field, which is a very small close. As a cyclist I don't want the punctures and if a child or senior resident fell on this it would cause serious harm. Can the refuse collectors please take more care and check their equipment as it seems to be leaking glass. And maybe do as I have done...sweep it up (see photos of what I collected after this week's bin collection), thank you. DO NOT SEND ANYONE...I HAVE CLEARED IT UP.
