Bowie adds 100m title to Olympic silver, China's Lyu sets javelin throw Asian record
Women's heptathlon saw Olympic champion Nafissatou Thiam of Belgium snatch the title with a total of 6,784 points.
Carolin Schafer of Germany got a sliver medal with 6,696 points. The bronze went to Anouk Vetter of the Netherlands, who finished with 6,636 points.
In other events, New Zealand's shot putter Tomas Walsh secured the men's title at 22.03 meters and Joe Kovacs of the United States settled for the silver at 21.66. Stipe Zunic of Croatia bagged a bronze medal with 21.46.
Ekaterini Stefanidi added a pole vault world title to her Rio Olympic glory by clearing a world-leading 4.91m.
American Sandi Morris won silver in 4.75 and Venezuela's Robeilys Peinado took bronze in 4.65.
Before the night session started, several medal ceremonies were held.
While American Justin Gatlin attended the medal ceremony at the London Stadium, he was booed again quite like Saturday when he grabbed the 100m title from 11-time world champion Usain Bolt.
Gatlin who last won the title at 2005 world championships was overlooked for his surprise win and his celebration was ruined by loud booing from a sell-out 60,000 spectators Saturday while bronze medalist Bolt, in his farewell world championships, received a hero's treatment.
The scene repeated on Sunday when they were called to step on the podium to receive medals from IAAF President Sebastian Coe. With his two-spell doping ban that ended in 2010, the 35-year-old Gatlin has never stopped fighting controversies and it looks that the stunning comeback win is not able to change the situation.
In an earlier medal ceremony, British heptathlon athlete Jessica Ennis-Hill was given the gold medal from the 2011 Daegu world championships after Russian rival Tatyana Chernova was stripped of the title for doping.
