The gunman behind the massacre at the Pulse nightclub in Orlando, Florida visited the venue on Saturday prior to carrying out the deadliest attack in US history, local media reported on Tuesday.
The attacker, US national Omar Mateen, paid a fee to obtain a wristband for the night club entrance, CNN reported citing law enforcement officials.
The US authorities believe Mateen entered the venue to assess the security situation at the club, according to the news outlet.
In addition, the day before the attack the gunman bought three plane tickets for himself and his family to fly to San Francisco in July, according to media reports.
On June 12, Mateen attacked a gay nightclub in Orlando killing 49 people and injuring more than 50 others. Mateen told police during the attack that he pledged allegiance to the Islamic State terror group, outlawed in many countries, including the United States and Russia.
