THIS is the jaw-dropping moment pair of brothers aged three and five dangle over a tower block drop after being left home alone.

Nail-biting footage recorded in Hong Kong shows the older boy sitting on an air conditioning unit dangling his tiny legs over the huge drop.

Meanwhile, the younger brother sits on a ledge of the high-rise apartment under the family’s flat – as police beg him to crawl back to safety.

The shocking footage continues with the older boy seemingly unaware of the potentially disastrous danger they are both in.

But the younger child is visibly much more distressed than his older sibling, and can be seen wailing desperately before he is carried back up by police.

The Sun has chosen not to reveal the brothers’ faces or identity.

The boys had been left home alone by their parents and managed to escape their room by climbing out through an unlocked window.

Gobsmacked bystanders called police who urgently rushed towards the building and broke into the family’s flat.

The nearly-devastating incident took place on March 21 in the skyscraper-dense city of Hong Kong.

In the horrifying footage, police can be seen ushering the younger boy back to safety – and he eventually stands up on the narrow ledge and grasps the hand of one cop who hauls him to safety.

However, his unfazed older brother seems to refuse to budge despite pleas from cops – and this causes a rescuer donning climbing gear to rush to the scene.

The abseiling man lowers himself towards the kid, and ties the child to a safety line in order to scramble the pair of them to safety.

The brothers’ parents were only identified as 32-year-old Li and 29-year-old To.

They were found nearby soon after and arrested by cops.

According to police, the couple face up to 10 years in jail for child neglect.

In 2019, petrified window cleaners were rescued from a skyscraper cradle which was swinging “wildly out of control” in high-speed winds.

Shocking footage captured the dramatic incident unfold on the side of an Oklahoma City tower in the United States.

In February this year, two climbers became trapped at the top of a massive 200ft rock tower after their ropes got tangled by high winds.

The pair of rock climbers had climbed up a tall, slender pillar called the “Totem Pole”, which rises from the sea at Cap Hauy on the Australian island of Tasmania.
