A 10-year-old girl sparked an emergency search after she went missing while swimming in the sea near South Pier, say coastguard rescue teams.
The coastguard rescue helicopter 936 was called in from Caernarfon to help with the frantic search at around 6.15pm on Thursday May 26.
HM Coastguard Fleetwood, Lytham St Annes and Blackpool life boats, and Blackpool Police all helped with the search.
According to rescue teams, the girl was eventually found safe and well "paddling close to the water's edge" not far North Pier around an hour later.
A spokesman for the coastguard said: "We were called by the police to help search for a young girl who was last seen by her grandparents in the water.
"She was found safe and well at around 7.15pm by the police not far from where she was last seen and it seems that she had just wandered off.
"Remember to always keep an eye of your children when playing near or in the water."
Nobody was injured during the incident.
