Yes & no. This is a false widow (Steatoda nobilis), it has featured in the news....but then, so have "deadly, flesh eating" spiders, which this certainly is not! ;-)
This looks like a male, they are often caught wandering about looking for a mate. This can lead them into trouble, if you feel better doing so, just contain him in something & then pop him outside. Females are more likely to stick to their web that they make close to a hiding place/cover. They are less prone to going on long walks.
Both males & females survive just fine outside, understandably a lot of folk aren't keen on them being indoors. I put males outside, but don't really mind females if they aren't in the bedroom/bathroom. They can bite, but this is usually only when they are trapped/crushed against the skin, they are quite docile otherwise.
Yeah tabloids tend to exaggerate things quite a bit, I remember Blue Sharks off of the UK coast being headlined as "Maneaters" during the summer. Thankfully, reading the BBC article, which lead me to this site, suggest that if there have been any cases requiring amputations etc than it was more to do with the individual who was bitten or possible misidentification rather than the actual potency of the venom.
Even if I had not read about the GBH spree that the Daily Mail and its cousins accuse this species of going on, something about it does stand out probably the marking on the back triggers a warning sign that it is venomous and it looked exotic like no spider I had seen in my house before and then the False Widow stories came to mind. Your right about the docile nature, which I took as confidence, because I got quite close to him to take the pics and, unlike other house spiders, he never ran away and just stood still and posed for the camera. I put put him in a container and let him go in the garden but only a few feet away from the door so he probably good back in how he entered.
