Authorities in Colombia have arrested eight people on suspicion of being involved in the explosion of a homemade bomb at a shopping mall that killed three people.
The Defence Ministry said on Saturday that the arrests of four women and four men took place simultaneously in Bogota and the central city of El Espinal on June 17.
All are suspected of belonging to a previously unknown radical group called the Popular Revolutionary Movement. The group is also believed to be behind a series of smaller attacks in the capital in recent months.
A pamphlet began circulating on social media in recent days in which the group denied any involvement in the June 17 mall bombing.
Among those killed in the blast was a French citizen doing volunteer work in Colombia.
