Three people have been arrested on suspicion of conspiracy to murder after two men were found shot dead at two different locations in Cambridgeshire.
Police said they found the bodies of a 32-year-old and a 57-year-old after they were called to incidents on Wednesday evening.
They described the attacks as “targeted”.
In the early hours of Thursday, a 27-year-old man and a 33-year-old woman were arrested in Cambridge.
A 66-year-old man was also arrested in Worcester.
All three were arrested on suspicion of conspiracy to murder.
Detective Inspector Mark Butler said: “Tonight we have launched two linked murder investigations following the shootings of two men at separate properties in the county.
“These events will be shocking to local people and there will be understandable concerns within local communities, however, we are treating the attacks as targeted and there is no wider risk to the general public.
“There will be an increased police presence in the areas concerned today and officers and scenes of crime officers will be at the scenes throughout the day.

“Our thoughts also go out to the family and friends of the victims. Specially trained officers are in touch with them and they are helping our investigation.”
A car believed to have been used by the offender, a white Peugeot 208, and a shotgun have been recovered.
“Detectives are now beginning inquiries into how these events unfolded and we are appealing to anyone who was in either area and saw anyone acting suspiciously or a white Peugeot 208,” DI Butler added.
