Local resident Vaz Terdandenyan was texting on his cell phone before looking up to see the bear coming towards him.
He luckily had enough time to run back into his house and away from the loose bear, as television crews broadcast the incident live on local TV.
The bear had been spotted roaming loose in La Crescenta, California, and was being followed by news helicopter crews.
Watch the live broadcast below:
Terdandenyan later revealed that he was texting his boss to say he may be late to work due to the commotion caused by the bear.
"I got up this morning and heard the helicopter noises," he told KTLA.
"I was texting my boss, telling him I would be late for work. I see the bear coming up the stairs towards me, I turned back and ran for my life.
"I ran back into the house, I locked the door. My wife saw the bear coming after me, climbing the fence into my backyard."
The bear had reportedly been spotted in and around the Glendale area in recent weeks, but had not shown any signs of aggression towards residents.
The animal was eventually tranquilized and safely transported back into the Angeles National Forest.
Terdandenyan added: "You have to be prepared at any time, as a bear could run after you."
The 'Glendale Bear' has since had its own Twitter page set up on the social networking site, and has amassed over 650 followers.
