Last night many of you in many parts of Chandler’s Ford heard a police helicopter circling round for quite some time.
I think the answer is in this tweet, by National Police Air Service (NPAS).
“Assist with search for a vulnerable missing person.”
22.00 Eastleigh, Hampshire. Assist with search for a vulnerable missing person.
