"The person who planted the bomb has been arrested," Interior Minister Suleyman Soylu said in a statement broadcast by the official Anadolu news agency.

For his part, Turkey's Vice President Fuat Oktay said, "We believe that it is a terrorist act carried out by an attacker, whom we consider to be a woman, exploding the bomb.”

Oktay added that the explosion, which the authorities classified as a terrorist act, injured 81 persons, 39 of whom have since been released from hospitals.

Justice Minister Bekir Bozdag said: "A woman had been sitting on one of the benches for more than 40 minutes and then she got up."

"One or two minutes later, an explosion occurred," he said as quoted by A Haber television.

"All data on this woman are currently under scrutiny," he said.

It is also worth noting that Istanbul's tourist thoroughfare Istiklal has reopened to pedestrians, as per NTV news station on Monday morning.

Istiklal Street was hit during a 2015-2016 attack campaign targeting Istanbul and other cities, including Ankara. These bombings, which killed nearly 500 people and injured over 2,000, were mostly blamed on ISIS and outlawed Kurdish militants.

Istiklal Street in Istanbul's ancient district of Beyoglu is one of the city's most well-known thoroughfares.
