The couple who climbed the Empire State Building were taken into custody after the stunt, and reports say they appeared to get engaged at the top. They were identified in multiple outlets as Angela Nikolau and Ivan Beerkus, and police said no one was injured.

What happened

They climbed to the spire/antenna area, unfurled a pro-peace banner, and then one of them appeared to propose on a lower platform before they descended.

Afterward

Authorities took them into custody, and reports say possible charges could include trespass and reckless endangerment. The building said the incident was unauthorized but posed no danger to tenants, visitors, or observation deck guests.

Who they are

Several reports identify the pair as Russian daredevil climbers Angela Nikolau and Ivan Beerkus, who have been featured in coverage of rooftop/climbing stunts before.

TL;DR: they climbed the building, made a dramatic public display, appeared to get engaged, and were then detained by police.
