Comhairle nan Eilean Siar is reminding the public to continue respecting social distancing measures which remain in place despite the easing of Coronavirus restrictions.
Their message on Twitter and on Facebook was accompanied by a photograph saying this was the scene at Bayble Pier on Monday (June 1) .
They said: "We all have a responsibility to maintain the good practice which has thus far prevented the spread of Covid-19 in the Western Isles. The Comhairle has signs on all its piers. The public are reminded to pay attention to these safety notices."
On welovestornoway.com social media viewers commented that this behaviour risked a second wave of Covid-19 infection.
From last Friday in Scotland, members of two different households were allowed to meet up outdoors if you maintain social distancing. Groups cannot be bigger than eight, and people are "strongly recommended" not to meet more than one other household per day. Limits on the time spent outside for exercise were removed.
Murdo Macaulay, Area Commander with HM Coastguard Rescue Service added his own warning to the Council pleas. "Jumping into water of unknown depth whether off a pier or rocks is a hazardous activity. There are people killed and injured every summer doing this. We attended Bayble this weekend. Please stop and think."
