Police in WansteadÂ are mystified by bags of foodÂ shoppingÂ which are being left on the corner of Leicester Road and Hereford Road. The bags are from M&S and the Co-op. Who leaves them there? And who takes them away? Is it a guerrilla foodbank? Anyone who can shed light on the mystery is invited to add a comment here, or contact the Wanstead Safer Neighbourhoods Team directly.
