Prince William was hands-on with an investigation at a mock crime scene when he paid a visit to the Duchy College Stoke Climsland in Callington, Cornwall.

The Prince of Wales had headed back to the classroom to learn more about the school’s opportunities for young people in rural areas.

Upon arrival, William was welcomed to the campus by Duchy College staff and he participated in a CSI training exercise with students enrolled in its Military & Protective Services Academy.

Pictures show students actively involved in a mock investigation wearing protective clothing and equipment and speaking to the Prince of Wales about the case.

William showed enthusiasm and interest in the investigation by aiding the pupils with their case and getting involved with multiple tasks. At one point he was seen using an aluminium powder to reveal fingerprints at the crime scene and speaking to students about the course and training.

On social media, fans praised William for getting involved with the tasks at the college. One wrote: “Think it’s fantastic to encourage the youth to follow a career in trades!”

Another, referring to William’s official title, said: “Wonderful to see our Prince William, the Duke of Cornwall, in Cornwall.”

The Prince learned about how the college is providing opportunities for young people in rural areas which is part of the Stoke Climsland Farm Cluster, a group of 23 farms, including several Duchy farms, which are working together to create environmental change.

The college also specialises in running land-based degrees in Southwest England across a range of areas including equine science, agriculture and horticulture. As well as being a hub for agricultural studies, the college also provides 86 courses across apprenticeships, degree programmes and adult courses to help people foster a successful career.

As part of the visit, he also popped into a student-run café on campus and heard from students who are part of the Future Farm programme.

The land for the college was originally leased by the Duchy of Cornwall, to Cornwall County Council in 1984 as a new County Agricultural College and the site has expanded over time with the latest addition being the Future Farm facility.

A statement from Kensington Palace said that the land for Stoke Climsland was first leased by the Duchy of Cornwall to Cornwall County Council for a new county agricultural college in 1984, which has since expanded over time.

The Duchy itself has been a “long-standing advocate” for the school and its students.

The Duchy of Cornwall is the British royal family’s 700-year-old estate designed to provide income for the heir to the throne, and its vast holdings today span 130,000 acres across 23 counties in England and Wales. It encompasses farmland, property and commercial businesses.

William has notably dedicated some Duchy of Cornwall land to building homes for those in need via his Homewards campaign, which is focused on tackling homelessness.

ITV’s documentary which focuses on William’s wider homelessness project, is out later this month.
