Police are investigating a mile long trail of ‘human’ blood discovered at Andrew’s Docks in Hull.

The blood, which stretches for more than a mile, was discovered by a passerby who was fishing off the docks on Thursday morning.

After being alerted shortly after 11am, Humberside Police said they were concerned by the ‘substantial’ amount of blood and have launched major enquiries – including a search of the river by Air Sea rescue – in to the case.

Samples of the blood have also been sent away for DNA analysis.


‘Due to the substantial amount of blood found we believe the person may have sustained a severe injury of some description and may be in need of medical attention,’ Detective Inspector Joanne Roe said.

Anyone with information is asked to contact police on the non-emergency number 101.
