Police investigating reports that a baby had fallen from a ferry in Belfast Lough last night have arrested a 37-year-old woman on suspicion of wasting police time.
Detectives say the woman is assisting police with their inquiries at a PSNI station in Belfast.
A search was called off after police said they were satisfied that a child had not fallen overboard from a ferry last night.
The woman who was rescued from the water is in a stable condition at Belfast's Royal Victoria Hospital.
As a Stena Line Ferry, sailing from Scotland, was preparing to dock at Belfast harbour last night, the operators received a report that a woman and a child had fallen from the vessel.
Emergency services rushed to the scene and a search and rescue operation, involving the Irish Coastguard helicopter, was immediately launched.
The ferry company indicated that a woman and a child had fallen overboard. But as search teams resumed their operations this morning, police indicated that they could not confirm the reports that a child was missing.
