Ben Affleck went into protective dad mode while picking up his son Samuel from swimming lessons.
The 48-year-old dad of two was photographed clutching onto his 9-year-old while making their way to the car after practice.
The Justice League actor proceeded with caution as they walked past waiting shutterbugs ahead of the weekend, just days after a scary trespasser made his way onto the star's $20 million Los Angeles property.
Wearing jeans and a long-sleeved checkered shirt, Affleck looked tense and eager to get his child with ex-wife Jennifer Garner out of reach from the cameras.
At one point, he even got out his camera and appeared to film the photographers, who most likely began to drill the star about his rumored romance with Jennifer Lopez.
Affleck's probably on high alert because the suspect who scaled a fence and ended up in the Oscar winner's yard is still on the loose.
That's because authorities are having trouble identifying him.
A spokesperson for the LAPD tells RadarOnline.com that police are finding it difficult to find a suspect in the crime because he cleverly covered his tracks.

Affleck's home intruder was caught on tape, thanks to the paparazzi that was stationed outside his mansion on Tuesday in an attempt to get a picture of the actor with J Lo.
The suspect wore blue sneakers, a black jacket displaying “security” in gold lettering, and a mask.
Police told RadarOnline.com they are looking for a black male but that's all they got.
However, we've learned cops found a bike that they believe the suspect ditched near the scene before taking off on foot.
When police responded to the scene, the trespasser was long gone.
He could face a misdemeanor trespass charge if caught.
Meanwhile, his rumored girlfriend was thousands of miles away.
Hours after the news broke, J Lo was photographed looking concerned and clutching her phone while walking into a local gym.
Don't worry though, the singer is up-to-date with everything going on in Affleck's life because the two are reportedly in communication "every day" since their weekend getaway to Montana.
