Clerkenwell Green is besieged during the night by delivery riders who come to the ZAPP warehouse on the Green in order to collect their orders.  They loiter in groups of 20 on the Green shouting, playing loud music, smoking and drinking alcohol as they wait for their order to be prepared.  Payment per delivery incentivises the riders to speed off (on modified delivery pushbikes) to make the delivery and get back again for the next order asap.  It is unclear, what, if any background checks have been carried out on the riders who turn up at your front door at night. They litter, have no respect for the Green, the pedestrians who use the footpaths, the residents who live there and those who walk their dogs in St James's church grounds.  The riders use the church grounds as their toilet and often bring their own toilet roll.   More and more delivery riders are now coming to the Green and residents, dogwalkers and the wider community need to act now before it is too late.
