The search for missing teenager Kathleen Harkin resumed on Monday morning in Perth.
Initially hampered by thick fog, the search continued in earnest with fire and rescue crews, police and a helicopter all involved.
The 15-year-old was last seen near Woody Island in North Muirton on Saturday night.
Search efforts have so far centred on the river Tay, with searchers returning to the Bute Drive area this morning.
The police helicopter resumed its search from the air, while crews on the ground were initially faced with poor visibility in the face of thick fog.
Canoeists have also been sent out on to the River Tay to assist with the search.
