Hamas terrorists flew into Israel before killing at least 260 people at the Supernova music festival in the desert near Kibbutz Re’im during the murderous assault on Israel.
Two women at the London rally were spotted with the paraglider images on their jackets.
One was wearing a red top with a white neckline, a light blue face mask, blue and black trousers and was carrying a purple bag.
The second wore a black jacket.
A Met Police spokesperson sid: ‘Officers have arrested two women following an appeal to the public by our Counter Terrorism Command.
‘On Friday, 27 October we issued images of three women we wished to speak with in connection with an investigation into suspected terrorism offences at a protest earlier this month.
‘The appeal was widely covered by media and as a result two women who recognised themselves in the pictures came forward to a police station in south London today, 30 October.
‘The women, aged 29 and 44, were arrested on suspicion of inviting support for a proscribed organisation, contrary to section 12(1)(a) of the Terrorism Act 2000.
‘They are currently being held in custody under the Police and Criminal Evidence Act, at a police station in west London.
‘We continue to seek the public’s help to identify a third woman seen in social media footage of a pro-Palestine protest in Whitehall on Saturday, 14 October, with an image of a paraglider on her top.
‘She is described as dark skinned, wearing light brown trousers and a long-sleeved red top.
‘She initially had a blue denim jacket tied around her waist and later put this on over her red top. She is wearing a light blue medical face mask and a dark scarf or bandana around her head. She also has a dark red shoulder bag.
‘We are also still asking for the public’s help to identify a man seen waving a placard with the words ‘I fully support Hamas’ on it during a protest on Bond Street on Saturday, 21 October.
‘He has short hair, light skin and is wearing a blue jacket with a light top underneath, a light stripy scarf around his neck, and light trousers or jeans.
Commander Dominic Murphy, head of the Met’s Counter Terrorism Command, said: ‘My officers are working night and day with our colleagues across the country to investigate suspected terrorism offences committed in the real world and online.
‘I am grateful to the public who have reported information to us and I urge anyone who has information about the man and woman we are still seeking to please let us know. If the people in the pictures recognise themselves, I urge them to come forward so we can speak with them.’
Anyone who knows who these people are or has information that could help the investigation is asked to please report it in confidence online at gov.uk/ACT or by calling 0800 789 321.
