A second man has been arrested by detectives investigating the deaths of two young men whose bodies were found in a pond.

The 28-year-old, from Canterbury, Kent, has been held on suspicion of supplying controlled drugs, a spokesman for Kent Police said.

His arrest comes after a 54-year-old man was detained on suspicion of murder following the discovery of two bodies in Reed Pond in Canterbury on Monday.

The bodies are believed to be those of missing 17-year-old Hugo Wenn and Daniel Lloyd, understood to have been in his 20s. Post-mortem examinations are due be completed later, and formal identification has not yet taken place.

Police are working on the theory that the dead pair, both known as buskers in the Canterbury area, knew the 54-year-old suspect.

The two bodies were found almost 10 hours apart in the pond, which is located behind Howe Barracks.

The first, understood to be Hugo, was spotted by a member of the public at around 12pm and the second was found later by police divers. Tributes were paid to 6ft 3in "gentle giant" Hugo by friends and teachers at the Archbishop's School in Canterbury, which he left after sitting his GCSEs last summer.

He was described as an accomplished beatboxer who excelled in drama, sport and music at school. He went missing last Friday, prompting his friends to launch Facebook and Twitter appeals to locate him. He was supposed to have met friends at a pub in Canterbury but texted at 8pm, before they arrived, saying he was leaving.

His former headteacher, Michael Liddicoat, said there was a "sense of complete shock at this loss" at the school, adding: "In many ways, Hugo was a gentle giant who was about 6ft 3in so you couldn't miss him around school. He was fantastic with the younger students and he will be missed."

Reed Pond is on Ministry of Defence land but MoD officials ruled out any connection between the deaths and the Armed Forces. An Army spokesman said: "It is extremely sad news that two bodies have been discovered on the training area behind Howe Barracks in Canterbury."
