Two women police officers were killed Tuesday when they were trying to arrest a murder suspect in Manchester, police said.
One of the officers died immediately, while the other was sent to hospital but doctors failed to save her life.
"This is a heartbreaking time for the officers' families and colleagues, and our thoughts are with them," said Assistant Chief Constable Garry Shewan.
Cregan was later arrested when he walked into a police station in Tameside.
