Two people have been arrested over the fatal stabbing of a nine-year-old girl, Lincolnshire Police has said.
Police were called to Fountain Road in Boston on Thursday night, and subsequently launched a murder investigation.
During a news conference, Lincolnshire Police Chief Superintendent Kate Anderson described what happened as an “isolated incident”, and said she will not be releasing the name of the victim.
Chief Superintendent Anderson also appealed to the public to pass on any information they may have in relation to the incident.
Forensic officers were seen working at the scene on Thursday evening, before heading off in the early hours of Friday.
There was also a large object covered up in the middle of an alleyway, marked by small yellow signs and protected by police officers.
The death occurred in a commercial part of Boston with very few residential properties nearby, said Sky correspondent Frazer Maude.
Most of the businesses in the area are closed permanently or would not have been open at the time of the incident, he added.
