Hmmm. I've just cycled down to the allotment for a sunny afternoon of hoeing and weeding. And I've just returned - the site has been cordoned off with Crime Scene tape, and a nice police lady told me I couldn't go on there, and they weren't sure how long the tape would remain in place.
We were on the plot at around nine this morning, dropping off sweetcorn and French bean plants which I'd grown in the greenhouse. I was planning on planting them out this afternoon. The site next to ours had been taped off at this point, but not ours. SomeBeans took some photos, as we hadn't taken any for a while. I can only surmise that it's something rather more serious than the normal round of pilfering that goes on at our (and most other) allotment sites.
Hopefully we'll be back on the plot before the birds get to these.
UPDATE: All was open this morning, although no-one knows what it was all about - all the police would say was that it was "an incident". I've planted the sweetcorn and beans, and SomeBeans discovered the joy of hoeing.
