Saw this and had to report it, I don’t know if it is true, but here is what was said on the site, there is also a link. I hope his dad is ok. Now, this was posted by the sun and I don’t know if it is indeed fact or what, like I said, but it is an interesting read.

“The 20-year-old wore a low-cut blue jumper while visiting his dad Alan, who was recovering after an operation in Chelsea, West London.

Daniel is filming Deathly Hallows, the last in the series based on JK Rowling’s novels.

Let’s hope he doesn’t fluff his lines.”

*also* Dan was wearing the same shirt he was while he was at the TMS, so this could just be a story to ruffle some feathers. So, don’t let it worry you, I really do doubt it was anything dangerous. If it was his dad, then I hope he feels better. (He could have also been visiting his stunt double)
