Hollywood actor Dwayne ‘The Rock’ Johnson has met with the 10-year-old boy hailed as a hero for saving his younger brother from drowning using a technique he saw in Johnson's movie.

Jacob O’Connor came under the spotlight after reports emerged that he saved his two-year old brother, Dylan, using CPR techniques he saw in San Andreas. 

This after O'Connor had found him lying face down in a pool in their grandmother's backyard. 

In an interview with US TV station WXYZ, the 10-year-old explained how the incident unfolded. 

"I was turning on a show when the doors were opened. I went outside and saw Dylan lying there [in the pool].

"I pulled him out and then gave him compressions."

O'Connor then went to tell his grandmother what had happened and following this, the toddler was then rushed to the hospital. 

He further explained that he was able to save his brother after watching the disaster flick, which had a scene where Johnson saves another character's life. 

Jacob was super nervous and shy the whole time we hung out, so it was fun getting him to laugh and talk. He threw me for an unexpected spin when he showed up on set wearing a shirt that he proudly made with my bull insignia on the front and on the back was the picture of me holding our two puppies, Brutus and Hobbs, after I rescued them from our pool. Seeing that picture on this boy's shirt, got me in the gut. Eventually, we would lose Brutus to heaven, but it wasn't the picture of Brutus that made me tear up, it was the fact that this 10yr old kid, had a heart big enough to put our puppies on his shirt after he saved his little 2yr old brother's life. What a special day. What a special kid. Thanks Jacob for being awesome and for being the kind of person we all aspire to be. ~ DJ

"There was a daughter that was drowning and he had to get her out and save her using the same thing," he said. 

Following this heroic event, Johnson took to Instagram  to praise the young boy for his actions, and has now returned to the photo sharing site to post a number of snaps of himself meeting O'Connor n person.

He also shared a video in which he spoke to the camera about Jacob’s heroic actions, and revealed the boy had made a T-shirt with a picture of the star after he completed a similar heroic act in rescuing his two dogs from a pool.
