A police officer in an orange Humber rigid inflatable boat watches out for approaching vessels while a colleague scours the river bed for evidence from a crime. The flag that is shown (reproduced below) alerts mariners to divers in the vicinity.



Two further police officers wait on the shore for news from the diver by radio.



The police diver surfaces with the remains of a mobile ‘phone that has been thrown from a bridge. The police examine it before bagging it up to be sent for laboratory analysis.
