The 22-year-old shot 141 in the qualification round and 28 each in the semifinal and gold medal contest to bag the top honours.

Elated at the news, NRAI president Raninder Singh said, "Ankur has come up the junior ranks really well and finished a creditable 16th in a top field at the Shooting World Championships in Granada earlier in the year.
It may be recalled that in the Continental championship that began on November 1, Seema Tomar had won the woman's trap event and team gold alongside Shagun Chaudhary and Shreyasi Singh.
Then Manavaditya Rathore, son of Olympic silver medallist Rajyavardhan Singh Rathore, won the junior trap event.
India could have further bolstered its gold tally, but the team event in the double trap men event was cancelled due to inadequate entries from the Asian countries.
