Sierra Leone police have started the process of kick starting a probe in which one woman was killed and 90 others were injured during the weekend inauguration of the new president.
Some arrests have been made but no one has been charged so far, a police statement said.
Sierra Leone Red Cross Society spokesman Abu-Bakr Tarawally on Monday updated the number of injured to 90 following Saturday's crush at Freetown's main stadium.
"We can confirm that 90 people were injured at the stadium stampede on inauguration day, some suffered, fractures, injuries with severe bleeding and suffocation," he said.
According to stadium management, over 50,000 people attended the inauguration, far exceeding the stadium capacity of 45,000.
"Some fainted and collapsed at pavilions while others jumped to the pitch and suffered fractures,"
The deceased is a 50-year-old woman who travelled from Liberia to witness Julius Maada Bio being sworn in.
Bio took office in early April after a tumultuous election campaign, ending a decade-long rule by the All People's Congress (APC).
