Five men have been arrested over the alleged sexual exploitation of a teenage girl in Greater Manchester.
The arrests, made during police raids, follow allegations by a 15-year-old girl that she was raped by several men between July 2011 and September 2012.
The men were arrested at addresses in Bolton and Farnworth on suspicion of rape and conspiracy to rape.
They were subsequently released on police bail until 15 January, a Greater Manchester Police (GMP) spokesman said.
Earlier the spokesman said police "believed that some of those arrested are known each other".
Det Ch Supt Mary Doyle said the girl was being supported by officers while the allegations were being investigated.
"These are always difficult and complex investigations," she added.
"The individuals concerned do not use their own names - they will use a series of nicknames and not necessarily the same [ones].
"It has been a painstaking investigation in order to identify the ones we have [arrested]."
