A 13-year-old boy has been arrested by detectives investigating a spate of sexual assaults.
It comes after nine women were subjected to unwanted sexual touching over a five-week period in east London, the Metropolitan Police said.
The boy was bailed until late November pending further inquiries after attending a police station on Thursday.
The attacks were particularly clustered around Blackwall Way, in Poplar, and took place in the evening between September 6 and October 11.

Officers urged anyone walking alone, particularly women, to remain alert.
