Police are investigating a string of knifepoint robberies near the River Lea after eight attacks in just five days.
Four of the attacks took place in less than an hour in Hackney, Tottenham and Waltham Forest.
The suspects have used unnecessary threats and violence, attacking victims after they had handed over property.
There have been increased patrols in the affected boroughs and activity has taken place to reassure the community, including warning local residents, many who have boats moored on the river.
– DETECTIVE INSPECTOR PAUL RIDLEY, HACKNEY CID
