A police car and cordon is in place at Norwich Riverside (Image: Archant)
Police placed a cordon around a section of bushes next to Boots on Norwich Riverside's retail park over the weekend.
The tape covered almost all of the grassy area from Albion Way round to Wherry Way, near the Novi Sad Friendship Bridge.
At 5pm on Sunday, one police officer was manning the cordon, though an eyewitness said the tape and car had been present all day.
Walkways around the area remained fully open.
The cordon had been removed by Monday morning.
Norfolk Constabulary has been contacted for more information.
