A huge shark has been circling a city waterfront park for four days after drifting in from the sea.
Initial reports put the animal at up to 13ft with later checks settling on about 11ft 6in.
Coastguards tried to push it back out, but then stood down after scientists warned that forcing it could spark an attack.

Crowds have since packed the railings to film every splash.
The sightings take place at Bukhang Waterfront Park in Busan, South Korea, where an artificial channel opens onto the harbour.
A walker raised the alarm after spotting a dark shape close to a public path at 8.57am on Friday (18 Sep).
Maritime police sent a special sea rescue team, coastal boats and a patrol craft, with fire crews joining the cordon.
A Coastguard official said: “Sharks can be aggressive.
“Citizens should refrain from approaching the waters.”
Crews worked for about six hours with boats and deterrent gear, but the shark would not leave.
The National Institute of Fisheries Science then advised against herding it due to the shallow water, and the operation was called off at 3.15pm.
The city blasted out emergency texts telling walkers and nearby residents to stay alert.
The shark was seen again at 1.05pm on Saturday and it was still in the channel this morning.
It rises every quarter of an hour, shows a fin, slaps the surface and sinks, drawing gasps from onlookers on the bank.
About 8,800 people came on Saturday and about 10,000 on Sunday, four to five times the size of a normal crowd.
One visitor said: “I took the high-speed train to Busan just to see the shark.”
Food trucks rolled in and nearby cafes ran long waits as the park became what locals called the hottest spot in the city.
Staff put up shark-danger signs, limited viewing to 30 minutes, and broadcast warnings not to lean over or climb the railings.
Police stopped a man who threw raw chicken into the water to feed it, as reported by Need To Know.
A smaller fish about 3ft long was later seen deeper in the channel, sparking online claims that the shark had given birth, which officials have not confirmed.
The Busan mayor’s office said: “Many people must have been surprised.
“It is believed that the shark came to North Port in search of food, as warm-water fish have become more common in the area due to climate change.”
Scientists believe it is a dusky or copper shark, a requiem shark about 12ft long.
Officers are now waiting for the tide to take it back to sea and have asked the port authority to keep the warning signs in place.
