Staff and students at the school in which a reservist, who died over the weekend during a Territorial army assessment, have held a special assembly in memory of Lance Corporal Craig Roberts.
In a statement, Trinity College in Lewisham said:
The staff and pupils of Trinity School, Lewisham have been greatly sadden by the news of the tragic death Craig Roberts.
For the past two years Craig worked at Trinity as a teaching assistant and had become a much loved member of the Trinity community.
He showed dedication, commitment and great care for young people. In addition to his duties in lessons Craig ran a fitness club, taught Saturday morning revision sessions and helped lead residential trips.
He was very committed to the common life of the school. Craig was proud of his military commitment and communicated that pride to Trinity pupils.
We are pleased that Craig was able to be such a significant part of our community. We pray for him and for his family at this terrible time.
