A teacher has been struck off for sending a naked and sexually explicit picture of himself to a group of young women.
Nemiya Rookwood, 33, worked at Lincoln University Technical College when the offence took place in 2018.
At a Teaching Regulation Agency hearing, Rookwood denied 13 allegations and did not accept he was guilty of unacceptable professional conduct.
However, the panel found his actions brought the reputation of teaching into disrepute and said his conduct "fell significantly short of the standards expected of the profession".
